Document Summary
A set of genetic instructions for any organisms. Either rna or dna (but a vast majority are dna) Luca gave rise to the 3 domains of life, each are made of dna and over time mutations gave rise to variation: luca is also the origin of multicellular life. Viruses are an anomaly, we don"t know how they fit into the generation of life: they aren"t technically life, but this can change they"re a weird category. 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: horizontal gene transfer + transgenics (intentionally manipulating the genome, ex: huntington gene, doesn"t exist in flies but when placed into flies it functions. Bacteria genome is thought to have come from alpha-proteobacteria. Formation of eukaryotes: endosymbiosis between a bacterium + proto-eukaryotic host.
