Which of the following components is responsible for synthesizing RNA during transcription in eukaryotic cells?
A
DNA ligase
B
RNA polymerase II
C
Helicase
D
Ribosome
Verified step by step guidance1
Understand the process of transcription in eukaryotic cells, which is the synthesis of RNA from a DNA template.
Identify the enzyme responsible for catalyzing the formation of RNA by adding ribonucleotides complementary to the DNA template strand.
Recall that DNA ligase is involved in joining DNA fragments during replication and repair, not RNA synthesis.
Recognize that helicase unwinds the DNA double helix to allow access to the template strand but does not synthesize RNA.
Know that the ribosome is the site of protein synthesis (translation), not RNA synthesis, and that RNA polymerase II specifically synthesizes messenger RNA (mRNA) during transcription in eukaryotes.
