Verified step by step guidance1
Understand the basic requirements for viral replication: Viruses must enter a host cell and utilize the host's machinery to replicate their genome.
Consider the options provided: Killing or lysing the host cell is not a requirement for all viruses, as some can replicate without immediately destroying the host cell.
Evaluate the necessity of injecting the viral genome: Viruses must introduce their genetic material into the host cell to initiate replication.
Assess the replication process: The viral genome must be replicated by the host cell's machinery, as viruses lack the necessary components to replicate independently.
Eliminate options that suggest viruses can reproduce without living cells: Viruses are obligate intracellular parasites and require living host cells for reproduction.
