Solution
The correct option is C tRNA
tRNA molecules are unique RNA molecules during protein synthesis these molecules bring amino acids to the site of polymerisation and correctly position each amino acids on the basis of codon anticodon base pairing. The codons are present on mRNA molecule and anticodons are present on one arm of the tRNA molecule. Thus on one arm of tRNA, amino acid is present and on the other arm anticodon for that particular amino acid is present, then the anticodon of this tRNA will form hydrogen bonds with corresponding codon on mRNA, thus bringing the amino acid to the site of polymerisatIon. The tRNA molecules are called as adaptor molecules because they can bind with both the amino acids as well as RNA.
