aaronq · Answer

these for sure:

"by coded instructions contained in DNA", as in: DNA -> mRNA -> protein

"through the presence of organic catalysts", ribosomes catalyze peptide bond formation

But maybe also:  "by spontaneous bonding of amino acid".

it's a spontaneous process - energetically.
