Francois jacob and jacques monod studied escherichia coli (e. coli) bacteria by using lab experimentation. what revision to their initial hypothesis did they come up with?
a. the lac operon is repressed by allolactose.
b. e coli are unable to process lactose sugar.
c. all e coli operons are always turned on.
d. two operons control bacterial respiration.

Correct D). Two operons control bacterial respiration

Francois Jacob along with Jacques Monod was the two scientists who is known to work on Escherichia coli lac operon. It is responsible for the transferring and split down of lactose sugar and helps in controlling the bacterial respiration and act as a molecular switch.

Escherichiacoli is known to be the gram-negative bacteria that is found in the intestine of warm-blooded animals.

Hence, the correct answer would be option D.
