D
RNA polymerase
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.
Recall that transcription is the process where the information in DNA is copied into RNA.
Identify the enzyme responsible for catalyzing transcription, which synthesizes RNA from a DNA template.
Recognize that RNA polymerase is the enzyme that binds to DNA and assembles RNA nucleotides complementary to the DNA template strand.
Differentiate RNA polymerase from other enzymes like ribosome (which synthesizes proteins), DNA polymerase (which replicates DNA), and DNA ligase (which joins DNA fragments).
