In a Lac operon, a mutation in the first gene of a structural gene will directly affect the synthesis of:
The operator locus of the lac operon may undergo mutation. When it mutates, it precludes the repressor from recognizing and binding to the operator. Which of the following may likely result from this mutation?
Which of the following factors will not affect the regulation of lac operon?
Cells want to express lac operons only when needed because
The lac operon is involved in lactose metabolism in bacteria. It is activated under which condition?
How does IPTG differ from lactose in terms of its interaction with lac operons?
In the availability of lactose and the absence of glucose, bacteria express lac operon genes which encode enzymes for lactose uptake and metabolism. Lac operon is an example of:
