A Prokaryotic Operon is Composed of a Series of Adjacent

Question

A prokaryotic operon is composed of a series of adjacent genes under the control of:
A)the same promoter.
B)the same operator.
C)an inducible promoter.
D)the same operator and promoter.
E)None of the answer options are correct.

Accepted Answer

A prokaryotic operon is composed of a series of adjacent genes under the control of the same operator and promoter. The operator is the site where regulatory proteins bind to control gene expression, and the promoter is the site where RNA polymerase binds to initiate transcription. Having the same operator and promoter allows for coordinated regulation of all the genes within the operon.
