Oh, and with respect to the matter of peptide synthesis, this became possible as far back as 1963, when Robert Bruce Merrifield invented the solid phase peptide synthesis (SPPS) technique. His 1963 paper in JACS describing the technique, is the fifth most cited paper in the journal’s history. He was awarded for Nobel Prize in Chemistry in 1984 for this work.
The technique has of course been refined over the years, as new reagents and new reaction mechanisms were discovered, that proved to be of utility value in either speeding up the reaction process, or eliminating side reactions that produced unwanted impurities. Merrifield peptide synthesis is now sufficiently advanced a technique, that there exist automated units for performing said syntheses. You can, if you spend enough money on one of these units and the reagent supplies, dial in a desired peptide sequence, hook up the reagent supplies, and let the machine do the donkey work for you.
In short, you can think of a Merrifield peptide synthesis machine as a Turing machine for producing proteins. It will even, in sophisticated variants thereof, protect the sulphur atoms of cysteine molecules during the synthesis, then selectively deprotect them to allow disulphide bonds to be formed to order.
The fun part being, of course, that most of the mythology fanboys peddling their tiresome apologetics here, won’t even know that this technology exists, or anything about the scientist who made it possible. Basically, if a machine can produce insulin, who needs a cartoon magic man?
