(Oak Ridge) The second type of cloning, reproductive cloning, is where it gets interesting. This is the process used to clone Dolly. The process used in reproductive cloning is called "somatic cell nuclear transfer" (SCNT). In this process, scientists transfer genetic material from the nucleus of a donor cell from the animal to be cloned. This material is transferred into an egg whose nucleus has been removed.
