Backstory I have a character who goes back in time to plant an idea in the minds of government scientists during the 1930's. The idea is to analyze a DNA sample and recreate it for future use in the 90's. In my original idea the character went back later in history when computers and technology was more advanced and thus called for a sort of Artificial Intelligence to be created by the scientists to aid in the work, carry it on after their deaths and to help the future characters in the 90's.
Now that I've decided I want the plot to tie into the secret history around things like the Manhattan Project and such, I want this to be another top secret experiment taking place during the 1930's. That said the technology is too primitive to include things like AI and Genetic Analysis (as far as I know). So I need help in this area to fill in the fictional gaps with historic truth. This lab's job is to analyze and synthesize a DNA compound for future use in the 1990's along with a era equivalent "system" to replace this AI to aid and explain things to the 1990's characters. The plot point will no doubt be fictional, but I want the science grounded in reality.
Question Historically and Logistically what would be the highest form of technology available to scientists during the 1930 that people would use to analyze and create a genetic compound (similar to the mods in Bioshock)?
I'm not ruling out the government having "experimental" or bleeding edge systems they could employ for this.
Also it's fine if history is changed as well.
