Lac operon problem
The first model for the control of protein production was the lac operon. This system of feedback and negative regulation is used by bacteria, however, the general principles also apply to higher organisms. Another method of protein regulation involves the unwrapping of DNA.

Francois Jacob and Jaçques Monod figured out how bacteria controlled the production of an enzyme called beta-galactosidase. This system of feedback and negative regulation became the lac operon and was the first model for the control of protein productio
Jacques Monod and François Jacob work with how bacteria breaks large sugars into smaller pieces.

François Jacob talks about bacterial mutants that could not metabolize lactose. Using these mutants, Jacob and Monod figured out how protein production is controlled.
François Jacob and Jacques Monod were the first to discover how genes were turned on and off.
François Jacob talks about the relationship between DNA, ribosomes, and protein production.
François Jacob explains why Jacques Monod chose to work with the lactose system.
François Jacob draws out the control mechanism he co-discovered.
