In the “activation” of an amino acid for protein synthesis:

#SCPH28 | Zoology

leucine can be attached to tRNAPhe, by the aminoacyl-tRNA synthetase specific for leucine.
methionine is first formylated, then attached to a specific tRNA.
the amino acid is attached to the 5' end of the tRNA through a phosphodiester bond.
there is at least one specific activating enzyme and one specific tRNA for each amino acid.
