In the process of transcription in Eukaryotes, the RNA polymerase I transcribes -

1. Precursor of mRNA, hnRNA
2. mRNA with capping and tailing
3. tRNA, 5 srRNA and snRNAs
4. rRNAs – 28 S, 18 S and 5.8 S

Correct answer: rRNAs – 28 S, 18 S and 5.8 S

Solution

RNA polymerase I in eukaryotes synthesizes the major rRNA precursor that is processed into 28S, 18S, and 5.8S rRNAs. The other polymerases handle different RNA classes: Pol II makes mRNA, and Pol III makes tRNA and 5S rRNA.
