they were showing what they could, for comparison to the other algorithm-representation model of the other slides.

they chose the amino acids triplets... then showed a string of DNA (codons) and the PCR/electrophoresis was a visualization again of the strings of DNA... and make up fingerprints eventually with the protein they output.

the mathematical themes here are recursion, at least

Hmm cool, but the fingerprint/DNA collage doesnt really make sense, the "script" window seems to show the 60-something codons that matches the 20 different amino acids that makes up the proteins , and the middle part shows a PCR result in gel electrophoresis, a system of displaying DNA markers, (Admittedly sometimes referred to as DNA fingerprinting, but it doesnt actually have much to do with actual fingerprints..) In short, while these three things are linked in that they all have to do with living cells and identifications, there isnt actually any direct links, and, importantly no direct link to math..

Sure, math is used in genetics, protein folding and I guess fingerprint-recognition, but that particular slide made a mess of it.

He is getting better, but he took the 1984 reference too far, indirectly implying that the Bush administration codones torture for the sake of torture. Low blow.
