Multiple Choice

Which condition is associated with a virus described as having a capsid containing two enzymes and RNA that infects host cells to replicate and spread?

This describes retroviruses, which carry enzymes inside the viral particle to kickstart replication once they enter a cell. The genome is RNA, and the virion brings two key enzymes: reverse transcriptase, which converts viral RNA into DNA, and integrase, which inserts that DNA into the host’s genome. This setup lets the virus hijack the cell’s machinery to produce new viruses and spread. HIV is a retrovirus, so it fits this description perfectly. After HIV enters a host cell, it uses reverse transcriptase to turn its RNA into DNA and then uses integrase to integrate that DNA into the cell’s DNA, enabling ongoing replication and spread. Over time, infection weakens the immune system, potentially leading to Acquired Immunodeficiency Syndrome (AIDS) if not treated. Other viruses listed are not retroviruses and don’t carry these two enzymes in the capsid, so they don’t match this description.
