Question

chapter 18 & 21 test
how do viruses reproduce?
○ they divide by mitosis
○ sexually by external fertilization
○ replicate outside the host
○ insert dna into the host cell

Explanation:

Viruses lack cellular machinery for independent reproduction. Mitosis and sexual fertilization are cellular organism processes, and viruses cannot replicate outside a host. They infect host cells by inserting their genetic material (DNA or RNA) to hijack the host's machinery for replication.

Answer:

insert DNA into the host cell
