Multiple Choice
In the central dogma, which enzyme catalyzes transcription (synthesis of RNA from a DNA template)?
A
Aminoacyl-tRNA synthetase
B
DNA polymerase
C
Ribosome (peptidyl transferase activity)
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, which is the synthesis of RNA from a DNA template.
Recall that transcription requires an enzyme to catalyze the formation of RNA strands complementary to the DNA template.
Recognize that RNA polymerase is the enzyme responsible for catalyzing transcription by adding ribonucleotides to the growing RNA chain.
Differentiate RNA polymerase from other enzymes listed: Aminoacyl-tRNA synthetase attaches amino acids to tRNA, DNA polymerase synthesizes DNA, and the ribosome catalyzes peptide bond formation during translation.
