What is test tube cloning?

Test tube cloning, also known as somatic cell nuclear transfer (SCNT), is a reproductive technology where the nucleus of a somatic cell is transferred into an egg cell that has had its nucleus removed. This process allows the egg to develop into an embryo, effectively creating a clone of the organism from which the somatic cell was taken. The embryo can then be implanted into a surrogate mother to develop into a genetically identical organism. This method has been used in various species, including the famous case of Dolly the sheep, the first cloned mammal.
