DNA polymerase
B
Reverse transcriptase
C
RNA polymerase (DNA-dependent RNA polymerase)
D
Ribosome (peptidyl transferase activity)
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 that can read the DNA template and synthesize a complementary RNA strand.
Recognize that DNA polymerase synthesizes DNA, not RNA, and reverse transcriptase synthesizes DNA from RNA, so neither is responsible for mRNA synthesis from DNA.
Conclude that RNA polymerase (specifically DNA-dependent RNA polymerase) is the enzyme that synthesizes mRNA from a DNA template during transcription.
