In the context of the central dogma, which enzyme is primarily responsible for synthesizing mRNA from a DNA template during transcription?
A
DNA polymerase
B
RNA polymerase (specifically RNA polymerase II in eukaryotes)
C
Ribosome
D
Reverse transcriptase
Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Identify the process of transcription, where the information in DNA is copied into messenger RNA (mRNA).
Recall that transcription requires an enzyme to synthesize RNA from the DNA template strand.
Recognize that DNA polymerase synthesizes DNA, not RNA, so it is not responsible for mRNA synthesis.
Know that RNA polymerase (specifically RNA polymerase II in eukaryotes) is the enzyme that synthesizes mRNA during transcription by reading the DNA template.
