Introduction In biology, a "clone" simply means that an object, cell, or whole organism has the same genetic makeup as the original object, cell, or organism. Cloning means an organism is generated genetically identical from an existing organism through non-sexual means. Cloning simply means to make an identical duplication of genes, fragments of DNA molecules, organs, or cells. There are three different types of artificial cloning. They include gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning produces copies of gene segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning is another word for Somatic Cell Nuclear Transfer (SCNT) and is the cloning of human embryo for research. Animals, plants, and Humans can all be cloned.
One of the most important breakthrough’s in the history of cloning was the cloning of Dolly. Ian Wilmut and Kieth Cambell cloned the first animal from adult cells. On July 5, 1996 Dolly the sheep was born using the Roslin Technique. It took a total of two-hundred and seventy-seven attempts to clone Dolly before the clone was finally made in perfection. This experiment proved that it was possible for adult animals to be cloned. Dolly was cloned from the mammary gland cell of an adult animal. For the mammary cell to develop into a fetus, an egg was still required. Instead of the egg contributing to the genetic makeup of the Dolly it was only the mammary gland. The cloning of Dolly involved a…
