Number: 435/440
Name: Chemistry: molecular biology and microbiology > Process of mutation, cell fusion, or genetic modification
Description: Processes for (1) producing a mutation in an animal cell, plant cell or microorganism, (2) fusing animal, plant, or microbial cells, (3) producing a stable and heritable change in the genotype of an animal cell, plant cell, or a microorganism by artificially inducing a structural change in a gene or by incorporation of genetic material from an outside source, or (4) producing a transient change in the genotype of an animal cell, plant cell, or microorganism by the incorporation of genetic material from an outside source.
