Document Summary
Compare closely related strains as well as nucleotide compositions b). Horizontally acquired gene are not integrated into the genome therefore you can identify them as they would be on extra-chromosomal plasmid c). Horizontally acquired genes display significant homology to bacteriophage genes d). They would be a different size in comparison to the host gene in the host genome. Bacterial genomes vary from bacterial species to bacterial species. This does not refer to the house keeping genes which tend to be very conserved due to their similar function. Ended talking about gene loss and mycobacterium leprae versus it relatives m. mariunum and m. tb. M. leprae has only adapted to live in humans (specialist) and strangely armadillos. Turns out that m. leprae is still indemic in texas (people who eat armadillo meat still get leprosy) Mitochondria used to be a bacteria (alpha-proteobacteria) got inside another cell and over evolutionary time it became part of the eukaryotic cell.
