The correct option is D tRNA
A sequence of three consecutive bases in a tRNA molecule which specifically binds to a complementary codon sequence in mRNA is known an anti-codon. The specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed, and the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid. One end of the tRNA matches the genetic code in a three-nucleotide sequence called as anticodon. The anticodon forms three base pairs with a codon in mRNA during protein biosynthesis.
