Question

Which of the following characteristics is typically associated with helical capsids?
Options
A They are composed of 20 triangular faces and 12 points.
B Most helical viruses are enveloped, and all are RNA viruses.
Correct Answer
C They are typically naked and contain DNA genomes.
D Tobacco mosaic virus (TMV) is an example, and it is a DNA virus.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Under 'Helical capsid,' the document states: 'Most of the helical viruses are enveloped, and all are RNA viruses.' Option A describes icosahedral, and option D incorrectly identifies TMV as a DNA virus when it's an RNA virus.

Hint

Recall the general properties described for helical viruses, particularly regarding their envelope and genetic material.
