What Protein is Involved in Synthesizing Messenger RNA in Eukaryotes

Question

What protein is involved in synthesizing messenger RNA in eukaryotes?
A)RNA polymerase I
B)RNA polymerase II
C)RNA polymerase III
D)sigma factor
E)both RNA polymerase I and III

Accepted Answer

RNA polymerase II is involved in synthesizing messenger RNA in eukaryotes. RNA polymerase I is responsible for transcribing large ribosomal RNA genes, while RNA polymerase III transcribes small non-coding RNA genes. Sigma factors are involved in bacterial transcription, not eukaryotic transcription.
