How do scientists clone animals or human beings?
The depiction below illustrates both traditional fertilization (top) compared to human cloning (bottom - called "somatic cell nuclear transfer")
This donor cell comes from any cell in the human body - skin, bone, muscle, etc. The genetic material or information is inserted into an empty egg cell. The egg cell "resets" the genetic information to the state of a human embryo. Diagram credited to David A.
