A) repressor.
B) promoter.
C) operon.
D) operator.
E) regulator gene.
Operon
A functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.
Regulatory Sequence
is a segment of DNA where regulatory proteins bind to control gene expression by turning genes on or off.
Repressor
A protein that binds to specific DNA sequences to prevent the transcription of genetic information from DNA to messenger RNA.

Final Answer :
C
Explanation :
A cluster of prokaryotic genes under the control of one regulatory sequence is called an operon. Repressor is a protein that binds to the operator of an operon and prevents gene expression. Promoter is a sequence of DNA that initiates transcription of a gene. Operator is a region of DNA that acts as an on/off switch for gene expression. Regulator gene codes for a protein that controls the expression of one or more genes.
