Question
The lactose present in the growth medium of bacteria is transported to the cell by the action of
Options
A.Permease
B.Polymerase
C.Beta-galactosidase
D.Acetylase
Solution
Sol. [Key Concept: Lactose permease in the lac operon]
The lacY gene codes for lactose permease, a membrane transport protein that facilitates entry of lactose into the bacterial cell.
The lacZ product, β-galactosidase, hydrolyses lactose. Thus, transport is carried out by permease: option (1).
