In which step of the life cycle of a bacteriophage does the tail release the enzyme lysozyme?

Correct answer: C. Penetration

  • A. Attachment
  • B. Adsorption
  • C. Penetration
  • D. Injection

Explanation

The correct answer is penetration. During the penetration phase of the bacteriophage life cycle, lysozyme is released to break down the bacterial cell wall, enabling the viral genetic material to enter the host cell. The other options are incorrect because:Attachment: The bacteriophage only attaches to the bacterial surface, with no lysozyme release.Adsorption: This step involves binding to the bacterial cell but not the release of lysozyme.Injection: Although DNA is injected into the host cell, lysozyme is released during penetration, not injection.
