A review on transgenic animals

An animal that has successfully integrated modified DNA into its germ line is known as a transgenic animal. The transgene may be passed on to every progeny of such an organism. It is important to note that a transgenic individual's transgene is present in all of his or her cells. The capacity to insert foreign genes into the germ line and successfully express the inserted gene in the organism has enabled unparalleled genetic manipulation of animals. The knowledge acquired through transgenic technology may be used to virtually every area of contemporary biology, including developmental gene control, oncogene activity, the immune system, and mammalian development. Because particular mutations can be inserted into transgenic mice, precise mouse models for human genetic disorders may be created, as well as a systematic genetic dissection of the mammalian genome can begin.
