A segment of DNA in a test tube replicates and produces many copies of itself.What was probably in the test tube that enhanced this process?
A) a ligase
B) a restriction enzyme
C) DNA polymerase
D) an electric current

Question

Quizplus · Accepted Answer

DNA polymerase is responsible for catalyzing the replication of DNA. Without an enzyme such as DNA polymerase, DNA replication cannot occur efficiently, and the process would not have been enhanced. Ligase is used to seal nicks in the sugar-phosphate backbone of DNA, while restriction enzymes are used to cut DNA at specific sites. An electric current can fragment DNA and is not typically used for DNA replication in a test tube.
