Answer #1

The correct answer is - b. An HIV virus produces a large protein that contains multiple structure proteins and protease.

Additional Information:

Polyproteins are composed of several smaller proteins, which attached covalently and form a large chain of protein. During maturation , viral polyproteins are cleaved by the protease enzymes and exhibit different biological functions.

Example : The HIV genome contains 9 genes which produces 15 different proteins, all of these are synthesized as Polyproteins.
