Cloning can be define as the creation of an organisms that is an exact genetic copy of another. This means that every single bit of DNA is the same between two. This is use to make multiple identical copies of DNA, create or propagate an organism from a clone cell and reproduce or propagate asexually such as clone a plant variety or animal. Cloning has its advantages and disadvantages but most people opined human cloning is playing the role of god. There are many disadvantages of cloning such as uncertainty of science technology, losing the diversity of genes, great diseases and leading to extinction.
The disadvantage of cloning is uncertainty of science and technology. Science and technology cannot solve everything. Do you ever think what will happen if we allow cloning is widespread?. Will the results be controllable?. Scientist cannot promise they can controlled the cloning result. There are some potential crises lurking behind. The primary drawbacks to cloning are its ethical problems. Some scientist do a cloning for their own benefits which to make they on top of the world instead of giving the benefits to the society. In addition, many years ago, a scientist successfully clone a sheep. The cloned sheep was named Dolly and identical to the sheep which the genetic material was derived. However, Dolly died in 2003 (Ian Wilmut 1997 as cited in Betsy, 2008). Furthermore, in cloning Dolly, it resulted in the death of many embryos and newborns before success achieved which is 29 embryos were transferred to 13 sheep and only one became pregnant with Dolly. Therefore, unexpected in science and technology may damage the cloning. In a nutshell, cloning have many disadvantages than the advantages which are uncertainty of science technology, losing the diversity of genes and the great disease and leading to extinction.
