Question

Which enzyme breaks the DNA molecule?

Hint:

DNase is used extensively in molecular biology applications to remove DNA from samples, such as during the preparation of RNA for experiments or to prevent DNA contamination.

Answer 1

Step 1: The enzyme responsible for breaking down or cleaving the DNA molecule is called  (Deoxyribonuclease). DNase catalyzes the hydrolysis of phosphodiester bonds between nucleotides in the DNA backbone, effectively breaking the DNA molecule into smaller fragments. 

Step 2: DNase plays an important role in various biological processes, such as DNA repair, recombination, and the degradation of damaged or unnecessary DNA.
