Document Summary

James watson, francis crick, rosalind franklin: dna as a double stranded helix: walter gilbert and fred sanger: sequence dna through sanger sequencing, early earth was anoxic and used anaerobic respiration for energy but then the origin of. Life might have also generated from hydrothermal systems on the ocean floor where it is stable and has abundant energy supply. Chloroplast from stable engulfing of a photosynthetic cyanobacterium cell. Repeated genes get affected by the community of bacteria surrounding them and nonessential/non-functional genes are deleted over time. Domain phyla class order family genus species: the two taxonomic tools for defining strains that belong together are 16s rrna similarity and. Dna-dna hybridization organisms are from the same species if they have greater than 97% 16s rrna sequence similarity and greater than 70% dna hybridization. Firmicutes: gram positive, low gc actinobacteria: gram positive, high gc.
