GLOSSARY :: D ::
Degenesis: Exclusion of genes or genetic structures of an organism with the aim to acquire new characteristics of the organism. See Gene, Mutation, Chimera Art.
Differentiation: In the general sense, the increasing specialization of organization of the different parts of an embryo as a multi-cellular organism develops from the undifferentiated fertilized egg. Referring to cells, the development of cells with specialized structure and function from unspecialized precursor cells, which occurs in embryonic development and in the subsequent replacement of certain types of cell from persisting unspecialized stem cells. See also Cell.
Disassembler: A system of nanomachines able to take an object apart a few atoms at a time, while recording its structure at the molecular level. See Nanotechnology.
DNA (Deoxyribonucleic Acid): DNA molecules are long chains consisting of four kinds of nucleotides; the order of these nucleotides encodes the information needed to construct protein molecules. These in turn make up much of the molecular machinery of the cell. DNA is the genetic material of cells. The extent of the DNA molecule segment is usually measured by the number of nucleotide pairs it contains. See Nucleotide, RNA.
