Fuels are materials that react with other substances to release nulear or chemical energy as heat. Chemical fuels release energy via combustion. Nuclear fuels release energy by nuclear fission. Nuclear and chemical fuels are used for different purposes because of the complexity of deriving heat from them, the amount of heat generated and use in various applications.
Answer:
The correct answer will be option-B.
Explanation:
Transfer RNA or tRNA is the RNA molecule associated with the protein synthesis as it adds the specific amino acids to the nascent growing polypeptide.
The structure of the tRNA molecule resembles the shape of a clover leaf and is known as the clover leaf model. The structure contains hydrogen-bonded stems and associated loops. The stems include acceptor stem which posses CCA 3'-terminal group to attach amino acids. The anticodon loop contains an amino acid attachment site. T and D loop contains modified pseudouridine and dihydrouridine.
Thus, Option-B is the correct answer.
