Cloning became to be, as a Finn Dorset ewe would provide the mammary cell for the cloning process. Secondly the mammary cell containing all copies of every gene that is needed to make the sheep. Although the only genes for proteins that are required by mammary cells are active. Thirdly the cells grow and then they are divided, by making carbon copies of themselves. But if the cells are starved of there nutrients, they will soon enter a quiescent state. When it gets to this point all of their genes are most likely already activated. In the fourth stage there is an egg from a Scottish Blackface ewe that provides the egg. Then in the fifth stage the egg or oocyte, is being kept alive in a laboratory dish. Sixth, the nucleus is taken from the egg. Seventhly, the mammary cell and the egg are fused with a bolt of electricity. The molecules that are in the egg then begin to program the genes in the mammary cell to produce the lamb embryo. Then in the eight stage the clusters of the embryonic cells are finished processing. In the ninth stage the embryos are inserted into the surrogate mother. Finally the tenth stage where the lamb is a result of a clone of the donor ewe. That lamb was Dolly. Dolly was the first mammal cloned from a cell from an adult animal
             This all relates to Chemistry because Chemistry involves finding cures, doing experiments, and combining chemicals. The way scientists started doing cloning was through Chemistry by experimenting with different chemicals to get the right reaction.
             One reason people have given for the invention of cloning is to make spare parts in the future. Once an embryo has been twinned, one embryo can be implanted and allowed to develop into a baby, while the other is frozen. If the child later develops an illness such as leukemia, then the frozen twin could be thawed and implanted into a surrogate mother, to be culled for spare parts after a few months' gestation. It is also believed that th...
