Solution

The correct option is A (A)→(4), (B)→(2), (C)→(3), (D)→(1)
tRNA is involved in the transfer of amino acid from the cytoplasm to the ribosome
mRNA is involved in the transfer of genetic information from the DNA to the protein.
rRNA is synthesised in the nucleolar organising region.
Peptidyl transferase is involved in the linking of amino acids by forming the peptide bonds between 2 adjacent amino acids.
