Q155
Repressor protein binds to which site in Lac Operon model?
A.
Regulator
B.
Promoter
C.
Operator
AnswerD.
Any of the above
Answer: Option C
Solution
Answer: Option C
Solution:
Repressor protein binds to the operator site in the Lac Operon model.The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.
The operator site where the repressor binds is a DNA sequence with inverted repeat symmetry. The two DNA half-sites of the operator together bind to two of the subunits of the repressor.
