Solution
The correct option is B is an anticodon
The tRNA (Transfer ribonucleic acid) helps mRNA in the synthesis of proteins and also in the transfer of amino acids at a specific location in translation. They join and form the chain of amino acids due to the bonding between the codons having three nucleotide bases. This structure in tRNA having three nucleotide bases is called an anticodon. The anticodons are specific for each amino acids and thus helps in sequencing and transport of specific amino acid on the mRNA strand and in the synthesis of proteins.
