Question

Based on the information provided, which of the following statements about virus structure is true?

a. all viruses are encased in a viral membrane.
b. the capsomere is made up of small protein subunits called capsids.
c. DNA is the genetic material in every type of virus.
d. glycoproteins can help a virus attach to the host cell.

Answer 1

The correct statement about virus structure is that glycoproteins help the virus attach to the host cell. Viral membranes, capsomeres as capsids, or DNA as the sole genetic material are not universal features of all viruses. The answer is option D.

Step-by-step explanation:

True Statement about Virus Structure

The statement that is true about virus structure is Glycoproteins help the virus attach to the host cell. Not all viruses have a viral membrane; therefore, option A is incorrect. The capsomere is indeed made up of protein subunits, but they are not called capsids, instead, the capsid is the assembly of capsomeres, making option b incorrect. Viruses may contain either RNA or DNA, so option c is also incorrect. Glycoproteins, which are present on the surfaces of some viruses, indeed facilitate attachment to host cells, making them critical for the viral infection process.
