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

Correct answer: Aminoacylation of tRNA

Solution

Aminoacylation of tRNA is the charging step that attaches each amino acid to its corresponding tRNA, making translation possible. This occurs before initiation, so it is considered the first phase of translation.
