Francois Jacob and drawing
Description:
Francois Jacob draws out the control mechanism he co-discovered.
In the 1960s, the control of protein production was figured out for a sugar metabolic pathway in bacteria. Bacteria turn on the production of an enzyme called beta-galactosidase when the sugar galactose is a food source. The mechanics of this type of genetic control are applicable to single-celled organisms like bacteria.
However, the general principles of how genetic control works also apply to higher-order cells.
