Question

Which component of the operon synthesizes the repressor protein?

Options

• Regulator gene (i)

• Promoter (p)

• Structural genes (z, y, a)

• Operator (o)

Answer 1

The regulator gene (i) is responsible for synthesizing the repressor protein. The regulator gene is not part of the operon itself but operates independently to produce the repressor that controls the operator.
