How does the cloning process work?

The word “cloning” is simply a term to describe Somatic Cell Nuclear Transfer (SCNT). Once cells are produced from the tissue sample provided by a genetic donor, they are combined with an enucleated oocyte (unfertile egg with the nucleus removed) and fused together using a process called electrofusion. The resulting embryos are cultured and transferred into recipient mothers within one week, with variation per species. “Dolly the Sheep” was the first mammal to be produced using SCNT cloning technology more than 20 years ago.
