What is the function of lysozyme released by bacteriophages?

Correct answer: C. Dissolve bacterial cell wall

  • A. Injecting DNA
  • B. Replication
  • C. Dissolve bacterial cell wall
  • D. All of these

Explanation

The lysozyme released by bacteriophages plays a crucial role in the infection cycle. Its main function is to break down the bacterial cell wall, specifically the peptidoglycan layer. This enzyme is usually present in the tail region of bacteriophages, and during infection, it helps the phage inject its DNA into the host cell by locally degrading the cell wall at the site of attachment. Later, at the end of the lytic cycle, lysozyme is again involved in breaking open (lysing) the bacterial cell wall to release the newly formed phage particles. Thus, lysozyme is essential both for entry of the viral genome into the host and for the release of progeny phages during cell lysis.

About Biodiversity and Variety of Life

Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
