DNA Cloning

Cloning is the creation of two organisms that is exactly genetically identical.

How Is It Done?

Somatic Cell Nuclear Transformation*- the process of cloning by removing the nucleus and it's DNA from an egg cell and placing the nucleus from a somatic cell into the egg cell. The egg cell then develops into an embryo and is placedinto a surgate mother.

Artificial Embryo Twinning- the process of cloning by separating an embryo into individual cells then letting the cells to grow and devide in a petri dish until they're placed in a surgate mother to finish delevoping into genetically indentical cells.

Natural Fertilization-when the sperm and egg cell combine, they create an embryo with two sets of chromosomes, one set from each parent.SCNT- the single chromosome set is removed from the egg cell and is replace by two sets of chromosomes from the somatic cell.

Cloning Myths

.

Scientisits are able to use cloning in many different ways. There has been speculation if dinosaurs could be cloned, and scientisist have confirmed it is possible, but unlikely to happen because a well-preserved sample of the extinict creature's DNA is needed. They also talk about cloning livestock. These animals would not be used for consumption though, but for breeding.

Clones happen instantly- Clones are created from embryos, so they need time to grow and develop before the clone is complete.The clone is exactly the same as the original- This is true for it's DNA, but it's appearance and personality depend on it's enviorment.

Cloning has been around for hundreds ofyears. The first instance of cloning was in 1952, and they attempted to clone frogs and failed. The first sucessful clone was in 1984 when a lamb was born from cloned sheep embryos. The birth of Dolly the sheep was the first clone made from adult cells. In more recent years, scientists have attempted cloning humans.
