Question

Eukaryotic RNA polymerase-III catalyses the synthesis of

• A. m-RNA
• B. 28S rRNA
• C. 18S rRNA
• D. 5S rRNA

Answer 1

The correct option is D 5S rRNA

RNA polymerase enzyme is involved in transcription. In eukaryotes, there are three types of RNA polymerases:

• RNA polymerase–I for 28S rRNA, 18S rRNA, 5.8S rRNA synthesis.
• RNA polymerase–II for mRNA synthesis.
• RNA polymerase–III for tRNA, 5S rRNA, snRNA synthesis.
