Question : Gene encoding RNA Polymerase I and III have been affected by mutation in a cell. Explain its impact on the synthesis of polypeptide, stating reasons

The correct answer is – The process of translation will not happen, thus the polypeptide synthesis is stopped/ hampered.
The reason for the above is: RNA polymerase I transcribes rRNAs which is the cellular factory for protein synthesis. (½ Mark)
RNA polymerase III helps in transcription of tRNA which is the
adaptor molecule/ that transfers amino acids to the site of protein
synthesis
