Multiple Choice
In an overview of transcription, what is the primary role of RNA polymerase?
A
It removes introns from pre-mRNA and ligates exons to produce mature mRNA.
B
It unwinds the DNA double helix at the replication origin and synthesizes new DNA strands.
C
It transports amino acids to the ribosome by matching anticodons to mRNA codons.
D
It binds the promoter and catalyzes RNA synthesis by adding ribonucleotides complementary to the DNA template strand in the direction.
Verified step by step guidance1
Understand that transcription is the process of synthesizing RNA from a DNA template.
Recognize that RNA polymerase is the enzyme responsible for this process.
Know that RNA polymerase binds to a specific DNA sequence called the promoter to initiate transcription.
Recall that RNA polymerase catalyzes the addition of ribonucleotides complementary to the DNA template strand.
Remember that RNA synthesis occurs in the 5\(\rightarrow\)3 direction, meaning nucleotides are added to the 3' end of the growing RNA strand.
