Multiple Choice
In the overview of transcription, what is the primary function of RNA polymerase in protein synthesis?
A
It transports amino acids to the ribosome by charging tRNAs with their corresponding amino acids.
B
It adds a 3′ poly(A) tail and a 5′ cap to newly made RNA as part of RNA processing.
C
It translates the mRNA codons into an amino acid sequence by forming peptide bonds at the ribosome.
D
It synthesizes an RNA strand complementary to the DNA template by catalyzing phosphodiester bond formation during transcription.
Verified step by step guidance1
Understand the role of transcription in protein synthesis: Transcription is the process where an RNA molecule is synthesized from a DNA template.
Identify the enzyme responsible for transcription: RNA polymerase is the key enzyme that carries out this process.
Recognize the specific function of RNA polymerase: It binds to the DNA template strand and synthesizes a complementary RNA strand by catalyzing the formation of phosphodiester bonds between ribonucleotides.
Distinguish RNA polymerase's role from other processes: Unlike tRNA charging, RNA processing (adding 5' cap and 3' poly(A) tail), or translation, RNA polymerase's primary function is to create the RNA transcript.
Summarize the function: RNA polymerase reads the DNA template and builds an RNA strand complementary to it, which will later be used in protein synthesis.
