What is the phage that causes the lytic cycle called?
Correct answer: D. Both a and b
- A. Virulent phage
- B. Lytic phage
- C. Temperate phage
- D. Both a and b
Explanation
A lytic (virulent) phage infects a bacterium, injects its DNA, uses the host machinery to produce new phages, and causes the cell to burst (lysis), releasing many new particles. In contrast, a temperate phage can follow either the lytic cycle or the lysogenic cycle, where its DNA integrates into the host chromosome as a prophage without immediately killing the cell.

About Acellular Life
Viruses are acellular infectious particles whose capsid, nucleic acid and host-dependent replication distinguish them from living cells. HIV infection covers transmission, replication, effects on helper T cells, progression to AIDS, symptoms, prevention and treatment, while AIDS is the disease state caused by advanced immune-system damage rather than a separate virus.
