Once they infect a cell, they take over the machinery of the host cell to replicate themselves, killing the host. Would you call viruses living or non-living?
Assertion (A): Viruses can replicate and produce new viral particles. Reason (R): Viruses take over the machinery of the host cell to replicate themselves after infection.
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
Both statements are true from NCERT. NCERT states viruses can replicate (Assertion true) and “Once they infect a cell, they take over the machinery of the host cell to replicate themselves” (Reason true). The Reason explains HOW the replication in the Assertion occurs - through hijacking host cellular machinery rather than using their own.
