Document Summary
Thus far we have talked about enzymes and their roles in biological pathways. Dna: structure, organization and replication: enzymes are proteins with catalytic activity (they have an ability to facilitate a reaction of some type) Proteins may perform a variety of other functions in the cell as well. Where do those proteins come from: dna has the hereditary information and hold the function of the organism/the proteins it creates. How does the neanderthal (~50,000 y old) genome compare to modern humans: single nucleotide polymorphisms (differences, catalogued sites where all (or nearly all) present day humans have the same snp but differ from. Neanderthal: differ at 31,389 snps 87 proteins. At one point there were only 31 of them only 9 were able to breed. What makes this possible? (to answer these questions) The structure of dna - highly stable molecule.
