Multiple Choice
In an overview of transcription, what is the primary function of RNA polymerase?
A
It synthesizes an RNA strand complementary to the DNA template by catalyzing phosphodiester bond formation.
B
It joins DNA fragments on the lagging strand to complete DNA replication.
C
It removes introns from pre-mRNA and ligates exons together to form mature mRNA.
D
It transports amino acids to the ribosome by charging tRNA molecules.
Verified step by step guidance1
Identify the role of RNA polymerase in the process of transcription, which is the synthesis of RNA from a DNA template.
Recall that transcription involves creating an RNA strand complementary to the DNA template strand, ensuring the genetic information is accurately transferred.
Understand that RNA polymerase catalyzes the formation of phosphodiester bonds between ribonucleotides, linking them together to form the RNA strand.
Differentiate RNA polymerase's function from other enzymes involved in DNA replication (like DNA ligase), RNA processing (like spliceosomes), and translation (like aminoacyl-tRNA synthetase).
Conclude that the primary function of RNA polymerase is to synthesize an RNA strand complementary to the DNA template by catalyzing phosphodiester bond formation.
