Multiple Choice
In the context of the central dogma, which enzyme catalyzes transcription (synthesis of RNA from a DNA template)?
A
Aminoacyl-tRNA synthetase
B
RNA polymerase
C
Ribosome
D
DNA 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 RNA is synthesized from a DNA template.
Identify the enzyme responsible for catalyzing transcription; this enzyme reads the DNA template and synthesizes a complementary RNA strand.
Recognize that RNA polymerase is the enzyme that performs this function, unlike DNA polymerase (which synthesizes DNA) or ribosomes (which synthesize proteins).
Note that aminoacyl-tRNA synthetase is involved in attaching amino acids to tRNA during translation, not in transcription.
