Eukaryotic Transcriptional Activator

Introduction             Much of what was initially known about transcription came from pioneering prokaryotic transcription studies that followed the1959 discovery of RNA polymerase. During those earlier times, it was presumed that gene structure and transcription in bacteria were practically the same for eukaryotes. This later turned out to be incorrect since eukaryotic DNA assumes higher-order… View Article

The Reproductive System

Human’s reproductive system undergoes through a sexual reproduction wherein the sperm cells secreted by the male reproductive organ meets the egg cell which fertilizes inside a female reproductive organ. In the case of Human who are considered as viviparous kind of organism, we are considered as life-bearing organisms wherein the young organisms or babies spend… View Article

The Replacement and Cosntinuity Models

Paleonthropologists generally use the following 2 models to explain the origins of modern humans. The replacement model The continuity model        Each of these models has its basis that could be traced back to hundred of years ago. The two models would be discussed explicitly with the use of examples for easy understanding. The Replacement… View Article

The role of ghrelins

Ghrelin is a general name for a class of hormones found in the gastrointestinal tract of vertebrates. It is a preprohormone containing a chain of 28 amino acid peptides. During synthesis, a modification arises whereas n-octanoic acid is bound to one of its amino acids. This makes it capable of playing its biological role. Ghrelins… View Article

Topoisomerases Case

Topoisomerases are enzymes that can change the linking number of the DNA and therefore play a critical role in regulating cellular DNA topology. These enzymes enable cells to deal with the mechanical and topological problems associated with manipulating duplex DNA by introducing transient breaks in the phosphodiester backbone of a DNA molecule. This paper examines… View Article

Understanding omega-3’s

To-date, many studies have been conducted to validate and understand the effect of omega-3’s in primary and secondary prevention of cardiovascular diseases. Omega-3’s have attracted attention as potential triglyceride lowering and cardioprotective agents. They are a special group of polyunsaturated fatty acids found abundantly in marine sources (fatty fish) as eicosapentaenoic acid (EPA) and docohexaenoic… View Article

The Plama Membrane

The plasma membrane exists in all living things for the simple reason that it serves vital functions without which the cell cannot survive.             The plasma membrane is composed primarily of a phospholipid bilayer which is made up of hydrophobic lipid “tails” that point inwards and hydrophilic phosphate “heads” that are positioned so that one… View Article

Translocation: Plant Physiology and Phloem Water Potentials

Transport system in a plant is concerned with the movement of materials from source to sinks. According to Lacher . W 1985, a source is a region of a plant, which is manufactures sugars during photosynthesis and supplies materials of any kind to the transport system (e. g leaves) and a sink as a region… View Article

Fruit Fly

This experiment focuses on the effects water bath temperatures have on D. melanogaster entering and recovering an anoxic coma. It was found that there was an indirect relationship between the amount of time it took D. melanogaster to enter and recover from an anoxic coma and the temperature of the water bath. D. melanogaster was… View Article

A World Without Water

Water is one of the essentialities of life on earth, without water life will not exist. Water is everywhere, we can find it from the foods we eat and beverages we drink. It has also many uses in our daily lives like cleaning ourselves, washing the clothes, watering the plants and others. Water can also… View Article

How Organism Evolved Physiologically

Organisms adapt to their environment but what happens when an organism’s surroundings and environment change? Physiological ecology is the study and understanding of that mechanism of living organisms and how living things work.

Diffusion and Osmosis Through Dialysis tubing

We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since… View Article

The Five Domains of Life: Biology

What are the major characteristics of each of the three domains of life? Why do some researchers believe that the Kingdom Protista should be split into more than one kingdom? In the early days of biology, all organisms were classified as either plants or animals. Single-celled eukaryotic organisms such as algae and Paramecium were assigned… View Article

Nature of Communities

At the beginning of the 20th century there was much debate about the nature of communities. The driving question was whether the community was a self-organized system of co-occurring species or simply a haphazard collection of populations with minimal functional integration (Verhoef, 2010). Krebs (1972) described a community as an assemblage of populations of living… View Article

Genetic Inheritance

To what extent does genetic inheritance influence behaviour? Use relevant research studies in your response. There is and has been for a long time now a controversy within the psychology science. This controversy states that until today psychologists can’t assure weather humans’ behaviour is inherited, or that it comes from the environment in which we… View Article

Diffusion Across Biological Membranes

From the cell simulation modal made, it has explained about the aspects of diffusion and indicator solution (chemical testing) to test for particular substances. From the observation made, iodine and glucose have greater concentration due to small molecular size and also they are monomers. It means their molecules are smaller. Thus, it diffused out to… View Article
