Solution

The correct option is C DNase
DNA synthesis is done with the help of Helicase, DNA polymerase, Ligase, and Primase enzymes. Ligase joins DNA strands called Okazaki fragments by catalyzing the formation of phosphodiester bond. Deoxyribonuclease or DNase is an enzyme that breaks the DNA into nucleotides, i.e. degrades the DNA. DNA polmerase is used to make DNA from nucleotides. RNA polmerase helps in replication. Hence, the correct answer is B.
