Question 7 • Biology - SC3209 IC

lyticlysogenic cell reproduces and spreads provirus

Answer
A
lytic
B
lysogenic

Explanation

In the lysogenic cycle, viral genetic material integrates into the host cell’s DNA as a provirus (or prophage). When the host cell reproduces, it copies that viral DNA and passes it to its daughter cells, spreading it without immediately destroying the host. The lytic cycle, by contrast, makes new viruses and typically bursts the host cell.
