What is the role of permease in the lac operon?
  1. Synthesis of the repressor protein
  2. Transcription of the operon
  3. Hydrolysis of lactose into its monomeric units
  4. Transport of lactose into the cell

Solution

In the absence of a preferred carbon source such as glucose, if lactose is provided in the growth medium of the bacteria, the lactose is transported into the cells through the action of permease.
