Answer: 3. Aminoacylation of tRNA

Key idea: Translation begins with charging of tRNA.

The first phase is aminoacylation: an amino acid is activated by ATP and linked to its tRNA by aminoacyl-tRNA synthetase. Only then does the charged tRNA take part in initiation, where mRNA binds the ribosome and anticodon recognition occurs.
