This field of creativity is based on the use of certain genetic and biochemical methods in contemporary art practice, among them neogenesis (correcting the genetic code by exerting influence of amino acids that, though existing in nature, have never been used by terrestrial forms of life to form an organism), degenesis (knock-out of the genes or genetic structures to obtain new characteristics of an organism), and transgenesis (removal- or artificial synthesis--of genes or genetic structures from the cells of an organism and their implantation into the cells of different organisms).
