Question

Which of the following is a function performed directly by RNA molecules during gene expression?

reading a DNA template to make an RNA transcript

catalyzing the formation of bonds between amino acids

replicating DNA

catalyzing the formation of bonds in a sugar-phosphate backbone

turning on a gene by binding to its promoter

The correct answer is :catalyzing the formation of bonds between aminoacids.

Reason: The peptide bonds formed between aminoacids in prokaryotes are catalyzed by ribozymes that are 23S ribosomal RNA.
