Q. Consider the following statements: (A) During translation, amino acids are activated in the presence of ATP. (B) During aminoacylation of tRNA, activated amino acids are linked to their cognate tRNA. Select the correct option
A) A is true, B is false
B) A is false, B is true
C) Both A and B are true
D) Both A and B are false
Explanation
During the first step of translation, amino acids are activated in the presence of ATP because formation of peptide bond requires energy. Later these activated amino acids link to their cognate tRNA and this process is called charging or amino acylation of tRNA.
