Answer:
The correct answer is a cofactor for enzyme activity.
Explanation:
Carboxypeptidase is a metallo-enzyme in which zinc is present at active site. It has been accounted for by Coleman and Vallee that the protein can be deactivated by the removal of zinc and that reactive again by the expansion of zinc, cobaltous, ferrous, nickel. which suggests that zinc is acting as the cofactor for this metalloenzyme. Zinc is a cofactor for up to 300 chemicals in the body. Proteins that utilization zinc as a cofactor is known as metalloenzymes.
Thus, the correct answer is a cofactor for enzyme activity.
Answer:
Since DNA is double-stranded, two different RNA molecules could in principle be transcribed from any gene, using each of the two DNA strands as a template.
Explanation:
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA
Answer:
D
