Solution(By Examveda Team)

The theory of 'Lac Operon' was given by Jacob and Monod and applies to only prokaryotes.
The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.
This lactose metabolism system was used by François Jacob and Jacques Monod to determine how a biological cell knows which enzyme to synthesize.
Their work on the lac operon won them the Nobel Prize in Physiology in 1965.
