Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

Transcription in eukaryotes are complex process and involves at least three different DNA-dependent RNA polymerases:

• The RNA polymerase I transcribes rRNAs of 28S, 18S, and 5.8S types,
• The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA).
• RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs)
