I would go with mathmatical formula because of physics and what not but I'm not completely sure so if you have a different possible answer you think would be better, go with that :)
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.
It would be the first one m.
Options are not provided in the question. I found the answer on the Internet.
Yes, deletion of the possible control elements can cause reduction in reporter gene expression. Due to deletion of a control element, the activator cannot bind to the enhancer. This causes reduction in the gene expression.
Answer: Deletion of element no. 3 causes a reduction in reporter gene expression.
Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.
