Anthropology 1: Human Evolution

Recombinant DNA technology is defined as a series of procedures that are used to recombine DNA segments. A recombinant DNA molecule is constructed from segments of two or more different DNA molecules. Under certain circumstances, a recombinant DNA molecule can enter a cell and replicate, either on its own or after it has been integrated into a chromosome. Some examples of DNA technology are the insertion of bacterial DNA into certain crops, cloning, and genetically engineered growth hormones. One can argue that these DNA technologies are controversial in relevance to product safety, ethical issues, environmental issues, animal welfare, and the issue over the experimental use of human embryos. As an anthropology student, I have come to the decision of being for recombinant DNA technology. Rather than being against.

It has been over two decades in which scientists have been utilizing methods of recombinant DNA technology. A common method that has been used is the insertion of human genes that direct the production of multiple proteins into bacterial cells in laboratories. In addition, the reformed bacteria can then produce human gene products. One example would be insulin. During the 1980’s diabetic patients relied on insulin taken from non-human animals. Although, the amount of insulin was not enough and some patients even become allergic to insulin. Since 1982, scientists have been using human insulin produced by bacteria. Not only is human insulin allergy-free, but also there is availability for all diabetics (Introduction to Physical Anthropology).

Another form of recombinant DNA technology is cloning. Taking this matter further, scientists have cloned mammals such as mice, rats, rabbits, cats, sheep cattle, horses, a mule and dogs. It has come to further notice that, researchers have recently created clones of dead mice that were frozen for sixteen years. One can argue that cloning gives scientists and...
