#3. Fundamental Processes
  1. leucine can be attached to tRNAPhe, by the aminoacyl-tRNA synthetase specific for leucine.

  2. methionine is first formylated, then attached to a specific tRNA.

  3. the amino acid is attached to the 5' end of the tRNA through a phosphodiester bond.

  4. there is at least one specific activating enzyme and one specific tRNA for each amino acid.
