A) DNA Polymerase
B) RNA Polymerase
C) Ligase
D) DNA Gyrase
E) Helicase

Question

Quizplus · Accepted Answer

RNA Polymerase is responsible for adding new ribonucleotides to the free 3' end of the growing molecule during transcription. DNA Polymerase, on the other hand, is responsible for adding new nucleotides during DNA replication. Ligase is involved in sealing nicks in the DNA backbone, and DNA Gyrase and Helicase are involved in unwinding the DNA molecule during replication and transcription.
