Solution
The correct option is C DNA Translation refers to the process of polymerization of amino acids to form a polypeptide. The order and sequence of amino acids are defined by the sequence of bases in the mRNA. The amino acids are joined by a bond which is known as a peptide bond. Formation of a peptide bond requires energy. Therefore, in the first phase itself, amino acids are activated in the presence of ATP and linked to their cognate tRNA- a process commonly called as charging of tRNA or aminoacylation of tRNA to be more specific. Translation begins when small subunit encounters an mRNA.
