Cloning is the natural or artificial process of creating separate organisms with identical or nearly identical DNA.
A clone is a cell, cell product, or creature that is genetically identical to the original unit or individual.
First clone:
Dolly, the sheep, was the first mammal to be successfully cloned.
Dolly was cloned by Roslin Institute associates in Scotland.
She was cloned from an adult somatic cell by the procedure of nuclear transfer from a mammary gland cell.
Dolly was created by cloning a mammary gland cell from an adult Finn Dorset ewe.
Dolly lived for a long time after her birth, with a functioning heart, liver, brain, and other organs produced genetically from an adult mammary gland cell's nuclear DNA.
The technology utilised to create her was eventually dubbed somatic cell nuclear transfer (SCNT).
