Create a 5 pages page paper that discusses genetically modified animals. By modifying the DNA of germline cells, it becomes easier for the modified DNA to be inheritable (Starr, Evers, & Starr, 2013). While introducing the foreign DNA, it is necessary to consider only those that have the capacity to differentiate into different cells of an adult animal.
Even though such cells are post-zygotic, they clearly represent a development phase characterized by incomplete separation of the germline and the soma (Starr, Evers, & Starr, 2013). In essence, such cells usually have the capacity to give rise to both the germline and somatic cells. Apparently, a transgenic animal is normally produced when a foreign DNA molecule is introduced into the cell of an animal through artificial means. The transgene (the foreign DNA molecule) may contain just one or several genes. The transgenic animal produced upon inserting a transgene into the already fertilized cells or the oocyte from the early embryo will be able to transmit the foreign DNA in its germline (Starr, Evers, & Starr, 2013). Genetic engineering pundits have created different types of transgenic animals, including transgenic fish, transgenic frogs, transgenic Drosophila, and a wide variety of transgenic mammals such as rats, mice, and livestock.
Gene targeting has been crucial to the process of genetic engineering considering that it is powerful and can influence the construction of an animal in which nearly all nucleated cells comprise a form of mutation, usually at the desired locus. Incidentally, gene targeting has only been possible in mice while efforts to employ it in other mammals have proven futile (Forman, 2010). The design of several new animals of human disease has been necessitated by the ability of the transgenic mice to perform specific changes in a prearranged or predetermined gene via gene targeting. In addition, another experimental approach that involves genetic manipulation of various animal species has highly influenced the genetic engineering procedure (Forman, 2010). .
