An unfertilized egg is then taken out of an adult ewe, and the eggs nucleus, along with its DNA, is sucked out. Thus leaving an empty egg cell that still has the cellular machinery to produce an embryo. The empty egg and the culture of the starved cells are then placed next to each other. An electronic pulse causes the egg and cells to fuse together, and a second pulse is given to start the cell division. ... Although scientists understand most of the cloning processes, how and why the DNA changes once inside the egg remains a mystery. ...

What Is Cloning There are three types of cloning that exist, reproductive cloning, DNA cloning, and therapeutic cloning. ... When you have a reconstructed egg after somatic cell nuclear transfer has been performed, it is then treated with chemicals or electric current to induce cell division. ... DNA cloning is the process of transferring a DNA fragment to an element such as a bacterial plasmid. ... In 1930 Hans Spemann proposed an experiment that would take the nucleus from a cell of a late stage embryo, a juvenile, or an adult and transplant it into an egg. ... King took a nucleus from ...

She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte (developing egg cell) that has had its nucleus removed. ... Scientists can simply take the DNA cells from the part of the body that's infected and take it to a lab to be developed. ... Then scientists remove the nucleus from unfertilized human egg cell and implant it in the cell. Shock the cell to make the cells combine and cause DNA to move back and forth and create the embryo; repeat until there is a sufficient amount of embryos, many...

Researchers protected the progress by saying they wanted to use the cloned embryos to harvest stem cells, rather than to create babies. Stem cells can be used to treat an immense amount of diseases, such as: diabetes, strokes, cancer, and AIDS. ... Well cloning allows people to turn any cell into an animal. Instead of injecting DNA into an egg, you can shoot DNA into cells in a petri dish. ...
