Question

Which statement regarding molecular movement (living character) of viruses is correct?

• A. Inactive until they infect some cell.
• B. Metabolism is absent in viruses.
• C. A virus does not grow in an artificial medium.
• D. Viruses do not respire

Answer 1

Answer:

A. Inactive until they infect some cell.

• The correct statement regarding molecular movement (living character) of viruses is:

• Inactive until they infect some cell.

• They are essentially inert outside a host cell, lacking the ability to replicate or metabolize on their own.

• Only when a virus infects a cell and hijacks its cellular machinery do they exhibit any signs of activity, including replication and the production of viral components.
