What is the main function of RNA polymerase during transcription?
A
To splice introns from pre-mRNA
B
To translate mRNA into proteins
C
To synthesize RNA from a DNA template
D
To unwind the DNA double helix
Verified step by step guidance1
Understand the process of transcription: Transcription is the first step in gene expression where a segment of DNA is copied into RNA by the enzyme RNA polymerase.
Identify the role of RNA polymerase: RNA polymerase is responsible for synthesizing RNA from a DNA template. It reads the DNA sequence and assembles a complementary strand of RNA.
Differentiate between transcription and other processes: Transcription involves the synthesis of RNA, whereas translation involves the synthesis of proteins from mRNA. Splicing is a separate process that occurs after transcription.
Recognize the steps of transcription: RNA polymerase binds to the promoter region of the DNA, unwinds the DNA double helix, and begins synthesizing RNA by adding nucleotides complementary to the DNA template.
Clarify the function of RNA polymerase: The main function of RNA polymerase during transcription is to synthesize RNA from a DNA template, not to splice introns or translate mRNA into proteins.
