D)reverse transcriptase
E)general transcription factors

Question

Quizplus · Accepted Answer

hnRNAs are synthesized by RNA polymerase II, which is responsible for transcribing protein-coding genes into pre-mRNA. hnRNAs are then processed and modified to become mature mRNA before they are exported from the nucleus for translation.RNA polymerase I transcribes ribosomal RNA genes, RNA polymerase III transcribes transfer RNA and small nuclear RNA genes, reverse transcriptase synthesizes DNA from an RNA template, and general transcription factors are proteins that are required for RNA polymerase to initiate transcription.
