The diagram shows how a cell obtains Nutrient A from its surroundings. Both Gene R and Gene S must function normally for the cell to successfully import Nutrient A.
What is the function of Gene R in this cellular process?
It acts as the physical site where the carrier protein is translated.
It is transcribed and translated to directly form the carrier protein structure.
It controls the expression of Gene S to regulate the production of the carrier protein.
It binds directly to Nutrient A to pump it across the cell membrane.
