DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information in humans and all other living organisms. Deoxyribonucleic acid is composed of four chemical bases: adenine, guanine, cytosine and thymine. The sequence of these bases within DNA encodes genetic information.
The production of exact copies (clones) of a particular gene or DNA sequence using genetic engineering techniques. The DNA containing the target gene(s) is split into fragments using restriction enzymes.
Animal Cloning is the process by which an entire organism is reproduced from a single cell taken from the parent organism and in a genetically identical manner. This means the cloned animal is an exact duplicate in every way of its parent; it has the same exact DNA.
