In recombinant DNA experiments, _____ is used to cut pieces of DNA, and _____ joins these segments to form recombinant DNA.
A)a restriction enzyme; DNA ligase
B)a RNA polymerase; a restriction enzyme
C)a DNA polymerase; DNA ligase
D)DNA ligase; a restriction enzyme
E)DNA ligase; a plasmid

Question

Quizplus · Accepted Answer

Restriction enzymes are used to cut DNA at specific sites, while DNA ligase is responsible for joining these fragments together to create recombinant DNA. RNA polymerases are responsible for synthesizing RNA, not manipulating DNA. DNA polymerase is responsible for replicating DNA, not creating recombinant DNA. Plasmids are small DNA molecules commonly used as vectors for cloning, but they do not play a direct role in cutting or joining pieces of DNA.
