Question

Bacteriophage release lysozyme at

• A. Absorption phase
• B. Penetration phase
• C. Eclipse phase
• D. Maturation phase

Answer 1

The correct option is B Penetration phase

Bacteriophage contains the genes for lysozyme enzyme. During penetration phase, the bacteriophage's tail secretes the enzyme lysozyme which breaks down the bacterial cell wall into segments. Therefore the break down of the cell by the enzyme lysozyme forms a hole on the host cell and the bacteriophage inserts the DNA into the bacterial cytoplasm. So the correct answer is 'penetration phase'.
