While isolating DNA from bacteria, which of the following enzymes is not used?

ALysozyme
BRibonuclease
CDeoxyribonuclease
Correct Answer
DProtease

Solution

Lysozyme is used for breaking the membranes which surround DNAs. Ribonuclease is used for removing RNA. Protease is used for removing protein. All these steps are necessary for isolation of DNA from bacteria. Doxyribonuclease would digest the DNA and hence is not used for isolating DNA from the bacterial cell. So, the correct answer is 'Deoxyribonuclease'
