Question

Identify the steps of the lytic cycle.


The pieces made in replication are assembled to complete the new virus particles.

The new viral nucleic acid and viral proteins are replicated.

The virus attaches to the host cell.

The original virus releases a protein that causes the cell wall to burst (lysis), killing the cell and releasing viruses.

The host’s DNA is disassembled and the virus takes over the cell’s metabolic activity.

Answer 1

Order and names of the lytic-cycle steps (with the sentences you gave matched to each):

1. Attachment (adsorption)
- "The virus attaches to the host cell."

2. Penetration (entry)
- The viral genome (and sometimes capsid) is injected or enters the host cell.
- (Your set didn’t state this explicitly, but it precedes takeover.)

3. Biosynthesis (replication/synthesis)
- "The host’s DNA is disassembled and the virus takes over the cell’s metabolic activity."
- "The new viral nucleic acid and viral proteins are replicated."

4. Assembly (maturation)
- "The pieces made in replication are assembled to complete the new virus particles."

5. Release (lysis)
- "The original virus releases a protein that causes the cell wall to burst (lysis), killing the cell and releasing viruses."
- (More precisely: newly made viral enzymes/lysozymes cause the host cell to lyse, releasing progeny virions.)
