Document Summary
Sequence pairs that cause different colors of eyes. Not only a vertical flow of genetic information down each branch. Horizontal gene transfer: genes can be passed between individual members of different species by non- productive mechanisms, such as conjugation, transformation and transduction. Transformation: bacteria uptake of dna from environment. Conjugation: the donor bacterium transfers dna to the recipient by mating. The evolution & diversification of life are the result of genetic changes. A set of genetic instructions for any organism. Function, but no heredity (can"t store genetic info) Implications of all organisms having similar genetic systems. Research findings on one organism"s gene function can often be applied to other organisms. Genes from one organism can often function in another organism. Endosymbiosis between a bacterium and a proto-eukaryotic host. It can result in genetic mergers and increase the complexity of a system: procedure, 2 distinct organisms both free-living unicellular & both have a genome, organism archaea feeds on bacterium.
