Question

The enzymes that are used to replicate a virus are synthesized by ______.

a. the host cell.
b. the virus capsid.
c. the virus capsule.
d. the receptor.
e. prions​

Answer 1

The enzymes that are used to replicate a virus are synthesized by the host cell. That is option A.

Process of viral infection.

A virus is a microorganism that has the ability to reproduce only by infecting a living host.

The main features of a virus include:

• capsid

• nucleic acid genome ( RNA or DNA)

• Envelope membrane

For a virus to be able to cause an infection,it has to pass through the following steps:

• Attachment of the virus to the host cell.

• Entry of the viral genetic material into the host cell

• Genome replication and gene expression: through the ribosomes of the host cells, enzymes are released which are used to replicate the invading virus to produce new ones.

Therefore, the enzymes that are used to replicate a virus are synthesized by the host cell.
