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
reading a DNA template to make an RNA transcript

replicating DNA
catalyzing the formation of bonds in a sugar-phosphate backbone
turning on a gene by binding to its promoter
Explanation / Answer
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.
