The answer to this is B....
A punnet square is a diagram that is use to predict an outcome of a particular cross or breed experiments. So base on the following data you have given, the possible answer would be that the punnet square data in horizontal are is RY, RY,rY,rY. In the vertical are is RY Ry RY Ry. I hope you are satisfied with my answer and feel free to ask for more
Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
