A long polypeptide that is cut up to generate several small proteins is:
Correct answer: A. Polyprotein
- A. Polyprotein
- B. Polymerase
- C. Polyisomerase
- D. None of these options is correct
Explanation
The correct answer is a) Polyprotein. A long polypeptide that is cut up to generate several small proteins is known as a polyprotein. Polyproteins are large precursor proteins that are translated from a single mRNA and later cleaved into individual functional proteins by proteolytic enzymes.
