During transcription, the enzyme that synthesises mRNA from DNA is:
ADNA polymerase (replication)
BLigase (seals nicks)
CHelicase (unzips DNA)
DRNA polymerase (transcription)
Answer & Solution
Correct answer: D. RNA polymerase (transcription)
RNA polymerase reads the DNA template 3'→5' and synthesises mRNA 5'→3'. DNA polymerase is for DNA replication; helicase unzips; ligase joins Okazaki fragments.
