Human cloning. Conceptual artwork showing identical foetuses on a DNA double helix, depicting human cloning. Cloning is a method of producing a genetically identical copy of an organism. It can be carried out by using the DNA from one individual to produce another individual. DNA (deoxyribonucleic acid) is the store of all genetic information. It is made up of two strands (purple and green) wrapped around each other, and held together by a sequence of bases. The sequence of the bases is unique in every individual, and determines the characteristics of the organism.
