An operon contains a ____.
A) single gene controlled by its own promoter
B) single gene controlled by multiple promoters
C) group of genes controlled by a single promoter

E) single gene controlled by its own operator
Operon
Group of genes together with a promoter-operator DNA sequence that controls their transcription.
Promoter
A region of DNA that initiates transcription of a particular gene, recognized and bound by enzymes and other proteins to start gene expression.
Genes
Units of heredity made up of DNA, acting as instructions to make molecules called proteins.

Final Answer :
C
Explanation :
An operon is a group of genes that are controlled by a single promoter. The promoter is responsible for initiating transcription of all the genes in the operon. The genes in the operon are often related in function and are transcribed together as a single mRNA transcript.
