which of the following statements about viral structure is true?
a. all viruses are encased in a viral membrane
b. the capsomere is made up of small protein subunit called capsid
c. DNA is the genetic material in all viruses
d. glycoproteins help the viral attachment to host cell

Answer :

In a viral structure, the capsomere is made up of small protein subunit called capsid. The correct option is b.

What is capsid?

Viral capsids are nanometer-sized canisters with complex mechanical characteristics that encapsulate the viral genome inside one host, transit it, and then release it inside another host cell.

Capsids are small protein subunits that make up the b. All viruses contain DNA as their genetic material. Glycoproteins aid virus attachment to the host cell.

Thus, the correct option is b.
