DNA

DNA was a genetic substance located in the cells of plants, animals, and microorganisms such as bacteria, viruses, and fungi. In animals, it was found in every individual and, with the exception of unaltered clone units and identical twins, was considered unique to each individual. The presence or absence of certain DNA segments could influence the appearance and physical health of an individual, and may even cause some natural mutations to occur in individuals or in populations. Manipulation of DNA was used as the basis in many different types of gene-altering procedures, most notably cloning, gene therapy, genetic hybrid creation and breeding (transmutation), and in the development of bioweapons.
