Detailed explanation-1: -Monozygotic (identical) twins are natural clones. Clones contain identical sets of genetic material in the nucleus-the compartment that contains the chromosomes-of every cell in their bodies. Thus, cells from two clones have the same DNA and the same genes in their nuclei.

Detailed explanation-2: -On Dec. 27, 2002, Brigitte Boisselier held a press conference in Florida, announcing the birth of the first human clone, called Eve.

Detailed explanation-3: -Identical twins have the same DNA as each other, but different from their parents. A clone, however, only has one parent and has exactly the same DNA as that parent. But even so, a clone isn’t a perfect copy. We now know that the way genes are turned on and off is greatly affected by the environment.

Detailed explanation-4: -Identical twins have two biological parents, while a clone has just one genetic host. Therefore clones may have one gestational mother and one or more social parents.
