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. RNA polymerase I transcribes rRNA genes, while RNA polymerase III transcribes tRNA genes and other small non-coding RNAs. Reverse transcriptase is an enzyme found in retroviruses and is involved in reverse transcription of RNA to DNA. General transcription factors are required for the initiation of transcription by RNA polymerase II, but do not directly synthesize hnRNAs themselves.
