Genetically Modified Animals
The Biology
Genetically modified (GM) animals are the result of deliberately changing a genome through genetic engineering. The process of modifying the genetic composition of a mammal scientist starts with Deoxyribonucleic acid (DNA). DNA makes up the genes of all living things and by using DNA sequencing scientist are able to identify a specific gene. Each parent passes along one set of genes, each set forming on side of the two sided DNA strand. The two DNA strands are known as polynucleotides. Similarities found between species prompt scientist to research and theorize utilizing variations found during research.
Ribonucleic acid (RNA) plays a part in the genetic engineering process because the RNA is a strand of nucleotides. The amount of research required to confirm the desired strand can be substantial, however once the RNA needed is identified, it can then be isolated, and replicated for further …show more content…
The eldest known and most common reason is for medical advancements. As early as the 1920 animal proteins have been used as pharmaceuticals, insulin extracted from pig pancreas is one of the first examples of such a use. Animals are modified to produce proteins for extraction, purification, and therapeutic use. In 2008 the FDA approved the use of GM goats that were engineered to produce human AT in their milk; AT is protein found in the human body and needed to assist in the blood clot process. (FDA Veterinarian, 2008) Scientis and medical professionals anticipated that other biological products, will be considered for production from animals such as goats, sheeps and cows. Rats, chickens, and pigs are among the other animals that have been used in research for medical
