Answer:B) protein
Explanation: Protein is the biomolecule synthesized in the ribosome. Protein is synthesized in a process known as translation in which the message encoded in an mRNA is translated into a polypeptide chain of a specific amino acid sequence in the ribosome. The polypeptide chain is then packaged in to protein through posttranslational modifications.
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.
