What is the process called when amino acids are linked to their cognate tRNA?
Options
- APolymerization
- BCharging of tRNA
- CPeptide bond formation
- DCatalysis
Correct answer
B. Charging of tRNA
Step-by-step solution
Translation refers to the process of polymerisation of amino acids to form a polypeptide (Figure 5.13). 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 specifi
