In the process of transcription in eukaryotes, the RNA polymerase I transcribes

Options

  1. AmRNA with additional processing, capping and tailing
  2. Bt RNA , 5 s srRNA and snRNAs
  3. CrRNAs-28 S, 18 ~S and 5.8 ~S
  4. Dprecursor of m RNA , h n RNA

Correct answer

C. rRNAs-28 S, 18 ~S and 5.8 ~S

Step-by-step solution

In the process of transcription (i.e. copying of genetic information from one strand of the DNA into RNA) in eukaryotes, the RNA polymerase I transcribes rRNA - 28S, 18S and 5.8S. On the other hand, tRNA, 5srRNA and snRNAs are transcribed by RNA polymerase III. RNA polymerase II transcribes precursor of mRNA, hnRNA.
