Genetics of Obesity

...Therefore in light of the above criticisms research has begun to more fully examine the extent to which an individual’s behaviour and/or environment can influence the development of obesity. As Barlow (2013) states that at a population level, the increase in prevalence is too rapid to be explained by a genetic shift; rather, it must result from changes in eating and physical activity behaviours that have shifted. A recent study by Kileser (2009) found independently of other factors, a positive...

Human Cloning

...To make this brief, I really am a skeptic so I am not easily sucked into the gravity or concreteness of the information/data I have acquired. I mean, I do not easily decide whether something should be approved or not. Being a student of course, is both advantageous and disadvantageous in understanding the concept of this topic. But I’m not saying that my understanding is limited only in a short extent. What I mean, is that I cannot give a definite answer to the question I am about to leave. In...

Genetically Modified Organisms

...Though we may not all have the same beliefs, there is one statement that stands out and should be remembered by us all: “God didn’t make a mistake, no matter how much we’ll strive or boast, trying to transform ourselves in creators, we can’t arrange things better than the way He did” (Sandu, 2010). There is so much technology that serves many outcomes to our people, our society, our environment, and our future. All in all, it’s important to always keep, not one’s, but everybody’s...

Positive and Negative Impact of Genetically Modified Food

...In recent years health professionals have become alarmed by the increasing number of bacterial strains that are showing resistance to antibiotics. Bacteria develop resistance to antibiotics by creating antibiotic resistance genes through natural mutation. Biotechnologists use antibiotic resistance genes as selectable markers when inserting new genes into plants. In the early stages of the process scientists do not know if the target plant will incorporate the new gene into its genome. By attachi...

......

Compare and Contrast the Processes of Mitosis and Meiosis.

...As for the life of flowering plants and mammals, it is a must that mitosis and meiosis are required in their reproduction. In flowering plants, their reproduction can be asexual or sexual. For asexual reproduction in flowering plants that requires mitosis, vegetative propagation is a common method which the vegetative parts of flowering plants develop into a lot of food stored. Asexual reproduction can occur by artificial vegetative propagation too, such as ‘cutting’. For sexual reproduction...

Pros and Cons of Genetic Engineering

...The pathogens can kill the target organism or could spread into the environment with unpredictable and dangerous consequences. Even crippled vectors can recombine DNA and therefore genes with their normal counterparts in their surroundings and thus suddenly and unpredictably become infective. | Molecular biologists acknowledge that they are only modifying one aspect of an organism's totality. However, they examine the organisms produced in detail, sometimes taking them through breeding programs ...

Oryx & Crake Discussion Questions

...In an article titled "The Prospect of Designed Genetic Change" he argued that freedom of choice would vindicate the new genetics, and set it apart from the discredited eugenics of old. To implement the older eugenics ... would have required a massive social programme carried out over many generations. Such a programme could not have been initiated without the consent and co-operation of a major fraction of the population, and would have been continuously subject to social control. In contrast, t...

GATTACA: 'Vincent is supposed to be weak. Yet his strength of character is the key to the story.’

...While the society in which Vincent lives in regards Vincent as weak and inferior, his character is both key to his success and the story as without his steely resolve and fierce determination there would be no story as society would continue to function as it was designed. Parallels can be drawn with Vincent’s plight and the journey’s of figures in our society like Oscar Pistorious. Gattaca serves to compound the message that has been passed down through generations by reasserting that you ...

The society of Gattaca

...Jerome is lucky enough to have superior genes, thus giving him the opportunity to achieve his full potential. Throughout his whole life he was expected to succeed at everything he was faced with, and being an Olympic swimmer, he was expected to win but “for the genetically superior, success is easier to attain. But is by no means guaranteed. After all, there is no gene for fate.” But what does this prove? Genes don’t change personality or fate, they just allocate your future for you in Gat...

Recombinant dna technology

...By providing vaccines otherwise unavailable to humans through biotechnology, many people experience longer then expected life spans. Usefulness of recombinant DNA technology in the worlds healthcare system can not be denied. However, the dependence on GM food in sustaining the world’s population should be examined more in depth. Has enough research been conducted on the effects of GMO’s on humans, animals, biodiversity, and the environment? I would disagree that sufficient data exists to be ...

Monsanto SWOT

...Protecting its intellectual property rights is very important for Monsanto’s business, particularly in the seeds and genomics segment. The company obtains and protects its intellectual property rights in jurisdictions in which the products are produced or used and in jurisdictions into which the products are imported. However, even if protection is obtained, competitors, farmers, or others in the chain of commerce may raise legal challenges to its rights or illegally infringe on the company’...

Are we humans the product of nature or nurture?

...With nurturing, people tend to observe others actions and behaviour, and try to be like others. As a result, the human behaviour is the result of experience and imitating. The social learning theory suggests that we learn through imitation and observation. It also suggests that people learn within the environment and get approval from the public by learning through an influential model. Bandura, a known psychologist found that according to this theory, a model can be the main cause for learning ...

Biology Lab Report “Independent Assortment & Dihybrid Cross"

...Although we know what to expect, the results are not always as seen. The chi-square results allowed us to sum up the class data total and acquire a p-value which would reject the null hypothesis because it was less than .05. This could be because the observed values of data were not exactly on point with the expected values. This is also because these estimates run on probability but at times, even probability seems to surprise the results given. The chi-square p-value results for sex in class t...

Seeds of Death Unveiling the Lies of GMO

...The documentary stimulated my listening and viewing literacies to a certain extent, as I stated earlier that there was a lot of repeated information given throughout the documentary. Although I enjoy watching documentaries, I prefer to read as I feel it is more captivating and can give you more information and details then what you get in a documentary. I found that the articles gave me more information about genetically modified organism than what the documentary had given me. I like that this ...

Genetic disease

...a) Which solution sample contained a single dye: S1, S2, or S3? How do you know? S3 contained a single dye because it only had one band. b) The molecular weights for the dyes are 452.38 atomic units (au) for orange G, 669.98 au for bromophenol blue, and 538.62 au for xylene cyanole. How do these weights compare with your original conclusions about the weights of the dyes? Base on the order of movement of the dyes through the gel (yellow moved the farthest, then purple, then blue), students shou...

Outline and evaluate biological explanations of obesity

...Participants were asked to assess their levels of hunger every 30 minutes, and it was shown that 5 out of the 6 participants used, showed that their ghrelin levels were closely correlated with degree of reported hunger. This was a lab study, with a high level of control, and easily replicable, so has high internal validity and reliability. However it is hard to determine whether the predicted levels of hunger stemmed from actual hunger, or social cues such as meal times and a person’s learnt e...

Cystic Fibrosis Case Study

...If I was in this situation, I would chose to adopt a child. The reason is there is a risk of having a baby with CF, and I wouldn’t want to take that small chance. 22. (Krickett) It seems to me that Sarah and Michael really want to have a child of their own. So, if I was them I would choose to get pregnant and continue with the pregnancy no matter what. Since there is not really a huge chance of their child getting CF then I would go ahead and see what the outcome would be when having the child...

An essay on dwarfism, telling the causes, symptoms, and treatments

...Although dwarfism may be detected with prenatal testing, most cases are not identified until after birth, by X-rays, and the child's appearance. The is no known way to correct the results of dwarfism, but some examples of treatments are joint, and hip-replacement surgery, which relieve the pain in joints by reducing the pressure, of the unbalanced weight. Another treatment is limb lengthening. In this process bones are cut, and pins are inserted between them, making them longer. Limb lengthenin...

World such as that depicted in "Gattaca"

...Gattaca is a captivating film that deeply explores the issues of genetic engineering, genetic discrimination and presents to the audience an example of a eugenic society. The film shows the world the possible outcomes of science and medicine dominating the world. It clearly portrays a society that may have taken medicine a little too far by making genetic engineering the norm. The film also teaches people that we cannot fully take genetic engineering as far as Gattaca. Genetic engineering shoul...

The advantages and disadvantages of cloning

...Overall I agree with cloning. Religious beliefs against cloning are very strong but there are many potential the benefits. If the techniques for cloning could be improved and the risks could be minimised, I believe cloning should be allowed. The cases where cloning could allow childless couples to have children when no other method is successful or where there are chances of transferring diseases cloning would be a great option. Also having the ability to study diseases and then being able to r...

Heredity, the Environment, and Development

...(Biological, Social-Environmental, and Psychological Dialecticism: An Integrated Model of Aging, 2000). As well with age innate biological changes impact our brain based on both shared and non-shared environmental experiences. A keen understanding of morbidity, mortality and how genetics influence both health and behavior are all important factors in how biological changes in the brain are associated with each stage of aging. Human behavior can be influenced by genetic pre-dispositions as well ...

DNA Replication Transcription and Translation

...Hence, the resulting mutation is “silent” for the amino acid sequence in the protein-ending gene is not affected. On the other hand, chromosomal mutations are triggered by the chromosomal rearrangements with alteration or non-alteration in the chromosomal number. Chromosomal mutations induce birth defects in humans such as in “cry of the cat” syndrome which involves deletion in the chromosome 5 and in Down syndrome which is caused by an extra copy of chromosome 21 (Enger, Ross, and Baile...

Genetic Engineering

...Using genetic modification to cure diseases and disorders is beneficial to parents, children, and society. However, using genetic engineering to create super-children with superior intellects and perfect features is wrong. Science and technology has its place in helping the human race. It should be used to save lives and improve the quality of lives. Using scientific research to appease parent's vanity hurts us as a race. It will create divisions between the "master-race" and normal people. It ...

GATTACA film analysis on the final scene

...Also, in the beginning of the film Vincent tells us how discrimination is no longer based on colour, religion, ethnicity or money but that it was _"down to a science"._ This is the only part of the film that shows different ethnicities as well as another female whereas throughout the film it was mostly dominated by white men in uniform. This does not make much sense, although a given a benefit of a doubt the final scene could mean that anyone as long as they have the perfect gene is able to fly ...

Biological approach to health and social care

...These are situations that can play a role in whether or not a person is feeling depressed., the biological perspective is often seen as limited, since it neglects other possible causes for behaviour, the impact of different cultural upbringings, mental states, and emotional desires. For example, it focuses too much on the 'nature' side of the nature/nurture debate. It argues that behavior is caused by hormones and genetics. One theory is that schizophrenia is genetic; however, twin studies show ...

Savior Siblings

...If PGD is deemed harmless it should be considered an acceptable way of finding a healthy stem cell donor that can save the life of another child. The family of Molly Nash faced a serious dilemma and ultimately made the right decision to resolve it. They ended up with two healthy children and avoided losing one of their children to a horrible disease. Why should we prevent such procedures when no harm was caused? We must be reasonable and consider the positive outcomes that come with a practice t...

Biological Theories of Crime

...The usage of hereditary understanding developed by the HGP is most likely to have memorable ramifications for both individuals and society. A number of the questions criminologists have raised about the function of genes in criminal behavior may be answered by the results of research started by the HGP. 7 In the area of crime-control policy, HGP-related information is anticipated to support the advancement of public policy options associated with criminal activity pre-vention and the treatment o...

Huntington’s Disease

...Other social problems involve marriage stability after diagnosis due to the fact that the children could also be affected as well as change of roles (HCS 26). From the above discussion it is clear that Huntington’s disease though rare, it has been causing concerns among social and medical fraternity. This is important as the social concerns have led to implementation of the Act against discrimination and this will in turn help the medical researchers who will be able to get more participants i...

DNA Worksheet

...DNA and RNA are long linear polymers that carry information in a form that can be passed from one generation to the next. In order to carry on a trait to the next generation the RNA polymerase has to bind with the promoter of the gene, which then opens the DNA double helix, from there a catalyzes the synthesis of the RNA molecule using one DNA strand as a template(Simon, Reece, Dickey, 2010). The RNA transcript is spliced to produce mRNA as the tRNA molecules picks up an amino acid, the first tR...

Fossil Evidence

...The second one I will explain is comparative anatomy. This also shows that organisms share a common ancestor, but proves it by the similarities of the organism’s anatomical structure. You look at the organism’s body parts and their anatomy and look to see if there is any connection between the organisms. There are two major concepts to comparative anatomy; homologous structures and analogous structures. Homologous is when the structures are similar due to common descent. While analogous is ...

Frankenstein and Human Cloning

...Today's cloning process, like the methods of creating life used by Dr. Frankenstein, arouses a controversy of morals and ethics from religious viewpoints. Cloning has a lot to do with the desires of man. Frankenstein desired to create life. Desires, otherwise known as temptations in these cases, bring us to a great fault. By taking the place of God, to make their own definition of a “person”, Frankenstein and the creators of cloning are defying God and going against the Bible’s moral stand...

Outline and Evaluate One or More Biological Explanations of Schizophrenia

...Further support comes from post-mortem examinations which have shown schizophrenia patients had a greater density of dopamine receptors in certain parts of the brain than individuals not suffering from schizophrenia (Owen et al 1978). However a problem with studies carried out into levels of dopamine and schizophrenia is that they carried out “post mortem”. Due to this we cannot say if the increase in dopamine is a cause or effect of schizophrenia. In addition brain-imaging studies have prod...
