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: -They are similar to identical twins, only born at different times. Just as twins share the same DNA, clones have the same genes as the donor animal. A clone is not a mutant, nor is it a weaker version of the original animal. Most cloning today uses a process called somatic cell nuclear transfer (SCNT).
Detailed explanation-3: -Gene cloning, which creates copies of genes or segments of DNA. Reproductive cloning, which creates copies of whole animals. Therapeutic cloning, which creates embryonic stem cells. Researchers hope to use these cells to grow healthy tissue to replace injured or diseased tissues in the human body. 08-May-2018
