Question

chapter 18 & 21 test
what happens after a virus has been taken up by the host cell?
○ it begins making protein
○ it divides
○ it inserts into the host dna
○ it switches to infectious mode

Explanation:

After a virus enters a host cell, the first key step for many viruses (especially retroviruses, and a common mechanism for viral integration) is inserting its genetic material into the host cell's DNA. While some viruses may later make proteins, division is not a viral action (viruses don't divide like cells), and "infectious mode" is not the accurate next step post-entry.

Answer:

it inserts into the host DNA
