Question

Which of the following phases requires lysozyme for the lytic cycle of viruses?

• A. Eclipse phase
• B. Latent phase
• C. Penetration phase
• D. Adsorption phase

Answer 1

The correct option is C Penetration phase

The important steps of the lytic cycle of the virus include attachment, uncoating, penetration, replication and release.
In the penetration stage, the enzyme lysozyme, located in the tip of the phage tail, degrades a small portion of the cell wall. The DNA in the head of the phage in injected into the cell and the phage coat remains on the outside.
Thus, the correct answer is option C.
