D
Helicase
Verified step by step guidance1
Understand the process of transcription, which is the synthesis of RNA from a DNA template.
Identify the enzyme responsible for synthesizing mRNA during transcription. This enzyme reads the DNA template strand and assembles a complementary RNA strand.
Recall that DNA polymerase synthesizes DNA, not RNA, so it is not involved in mRNA synthesis.
Recognize that reverse transcriptase synthesizes DNA from an RNA template, which is the opposite of transcription.
Conclude that RNA polymerase (specifically RNA polymerase II in eukaryotes) is the enzyme that synthesizes mRNA using a DNA template.
