Question

Quizplus · Accepted Answer

RNA Polymerase 2 catalyzes the initiation of transcription in most eukaryotic genes, including protein-coding genes, while RNA polymerase 1 transcribes genes that encode for ribosomal RNA molecules, and RNA polymerase 3 transcribes genes that code for different types of small RNAs. RNA polymerase 4 and 5 have been discovered in plants, but their exact functions are still under investigation.
