For a Prize Bull, Next Big Test Is in Genetics Lab

In this case, the host is an unfertilized egg whose genetic material has been removed through enucleation process.The biological process of nuclear transplantation is whereby scientists derive a cell from an adult animal they wish to clone. The genome of the animal is contained in the nucleus of this derived cell. Genome is the DNA that has instructions to create a new individual. The next stage in this process is taking an unfertilized egg from the female of the same species, and removing its nucleus (Mann, 2003, p. The scientists then put the nucleus into the egg; thus, basically replacing the DNA of the egg with that of the cloning animal. The nucleus derived from the donor cell is fused with the egg with the help of a smell electric current passed through the cell. Adding a series of chemicals into the egg tricks it into believing that fertilization is taking place. At this stage, the outcome may be successful or unsuccessful, if successful then division of the egg takes place with future development and growth determined by unique genetic commands coming from the transferred nucleus (Cibelli, 1998, p. Generally, a genetic copy of the animal donating the nucleus results from the growing egg. The cloned embryo takes several days or weeks to grow in the lab, but for it to develop into a baby animal, scientists insert the embryo into the uterus of the same species or closely related species resulting into reproductive cloning. The following picture is a typical cloning process.From the explanation of the scientific procedure, it is clear that the resulting animal from the nuclear transplant, the clone is identical to the adult animal that donates its gene. Therefore, this means that the two animals will have the same qualities and temperaments because of the identical genetic makeup. Hence creating a clone from Alcalde would result in offspring with the same genetic makeup, and so, the same superior qualities and uniqueness that Mr. Del Rio is hoping to preserve. Nevertheless, this scientific concept is controversial because it raises ethical issues.
