Question

What is the role of RNA polymerase III in the process of transcription in eukaryotes?

Answer 1

In eukaryote cells, RNA polymerase III (also called Pol III) is a protein that transcribes DNA to synthesize ribosomal 5S rRNA, tRNA, and other small RNAs.

Role of RNA polymerase III :

1. The main function of the third polymerase, Pol III, is the duplication of the chromosomal DNA.

2. DNA polymerases are involved mostly in DNA repair and translation DNA synthesis.

3. Together with a DNA helicase and a primase, Pol III HE participates in the replicative apparatus that acts at the replication fork.
