Question

Choose the type of RNA that is correctly matched with its form and function
$\begin{array}{cccc}& \text{Type of RNA}& \text{Form}& \text{Function}\\ \text{I}& \text{mRNA}& \text{Messenger}& \text{Carrier of information to ribosomes}\\ \text{II}& \text{rRNA}& \text{Ribosomal}& \text{Catalyses peptide bond formation}\\ \text{III}& \text{tRNA}& \text{Transfer}& \text{Transport of amino acids to ribosomes}\end{array}$

• A. I, II & III
• B. I and II
• C. II and III
• D. III only

Answer 1

The correct option is A I, II & III

mRNA or messenger RNA is the RNA molecule produced by the transcription of DNA. It carries the codons which are required for protein synthesis.

tRNA or transfer RNA molecule carries the specific amino acid from the amino acid pool to the ribosomes, for protein synthesis.

rRNA or ribosomal RNA are RNA molecules which are major structural constituents of ribosomes. They are involved in catalysing the formation of peptide bonds between amino acids during protein synthesis that takes place in ribosomes.
