Where does the repressor protein bind?
Operator
Promoter
Enhancer
Terminator
Answer
The operator is the specific DNA sequence where the repressor protein binds. The repressor protein is a regulatory protein that controls gene expression by binding to the operator and preventing RNA polymerase from transcribing the gene. When the repressor protein is bound to the operator, the gene is said to be repressed. When the repressor protein is not bound to the operator, the gene is said to be derepressed.
