In the central dogma, which enzyme catalyzes RNA synthesis during transcription from a DNA template?
A

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.
Identify the process of transcription, where RNA is synthesized from a DNA template.
Recall that the enzyme responsible for catalyzing the synthesis of RNA during transcription is RNA polymerase.
Differentiate RNA polymerase from other enzymes: DNA polymerase synthesizes DNA, aminoacyl-tRNA synthetase attaches amino acids to tRNA, and the ribosome synthesizes proteins.
Conclude that RNA polymerase is the enzyme that catalyzes RNA synthesis during transcription from a DNA template.
