- BAminoacylation of tRNA
- CRecognition of an anti-codon
- DBinding of mRNA to ribosome
Correct answer
B. Aminoacylation of tRNA
Step-by-step solution
The steps of the translation mechanism are: Activation of amino acids: In the presence of enzyme aminoacyl-tRNA synthetase (E), a specific amino acid (AA) binds with ATP. A A 1   +   A T P   → M g + 2 A m i n o a c y l   s y n t h e t a s e   A A 1 - A M P - E n z y m e   c o m p l e x   +   P P i b) Charging of tRNA: The AA 1 –AMP–E 1 complex reacts with specific tRNA. Thus, the amino acid is transferred to tRNA. As a result, the enzyme and AMP are liberat
