gene switching
gene switching
the process in which genes are activated or deactivated during development, so that there is a sequential output of gene products, some taking part in current biochemical pathways, others acting as inducers and/or repressors of other genes (see JACOB, F). see also CHROMOSOME PUFFS for physical evidence of gene switching.Collins Dictionary of Biology, 3rd ed. © W.
