Solution
The correct option is D Selection of amino acids
Transfer RNA, or tRNA, is a member of a nucleic acid family called as ribonucleic acids. RNA molecules are comprised of nucleotides, which are small building blocks for both RNA and DNA. tRNA is a specialized RNA molecule with a very specific purpose, to bring protein subunits (amino acids) to the ribosome, where proteins are constructed. Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. Each type of amino acid has its own type of tRNA, which binds it and carries it to the growing end of a polypeptide chain if the next code word on mRNA calls for it. The correct tRNA with its attached amino acid is selected at each step because each specific tRNA molecule contains a three-base sequence that can base-pair with its complementary code word in the mRNA.
Thus, the correct answer is option D.
