Which enzyme is helpful in weakening bacterial cell wall?

Answer and explanation

Correct answer: Lysozyme

Lysozyme breaks bonds between sugar units in peptidoglycan, the major component of the bacterial cell wall. This weakens the wall and makes bacterial lysis easier during DNA isolation. RNase degrades RNA, not the cell wall. Exam tip: associate lysozyme with bacterial cell-wall breakdown in DNA isolation.
