________ are Used for Cutting DNA Molecules into Fragments

Question

________ are used for cutting DNA molecules into fragments.
A) Antisense RNAs
B) Mutagens
C) DNA polymerase and DNA ligase
D) Restriction enzymes
E) RNA polymerases

Accepted Answer

Restriction enzymes are specifically used for cutting DNA molecules into smaller fragments. They recognize specific sequences of nucleotides and cut the DNA at those points. Antisense RNAs, mutagens, DNA polymerase and DNA ligase, and RNA polymerases are not used for this purpose.
