The first phase of translation is

The first phase of translation is
  1. Recognition of DNA molecule
  2. Aminoacylation of tRNA
  3. Recognition of an anti-codon
  4. Binding of mRNA to ribosome

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.

AA1 +ATP Mg+2Aminoacyl synthetase AA1-AMP-Enzyme complex + PPi
 
b) Charging of tRNA:
The AA1–AMP–E1 complex reacts with specific tRNA. Thus, the amino acid is transferred to tRNA. As a result, the enzyme and AMP are liberated. It is also called aminoacylation of tRNA.

AA1-AMP-Enzyme complex + tRNA AA1-tRNA + AMP + Enzyme
