How to make a clone - (don't try this at home)


  • First, the nucleus from an unfertilized egg containing the 23 chromosomes from donor woman is removed and replaced with the nucleus of an adult cell (often a skin cell) of the person to be cloned.
  • The egg is now fertilized, containing the exact same 46 chromosomes of the donor.
  • The fertilized egg is activated by an electrical charge and then begins the normal process of development.
    The new embryo, or blastocyst, is an exact genetic match to the donor.
  • The newly developed embryo can be used for two types of cloning: reproductive and therapeutic.
  • A blastocyst is an early-stage embryo between four or five days old, made up of about 150 stem cells.

Somatic Cell Nuclear Transfer (SCNT) is the scientific term for cloning. Many don’t want you to think that SCNT is really cloning, but do not be fooled. It is the same process, the only difference is how you use the clone.
