Document Summary
Important in disease: o-antigen stimulates the immune system, lipid a causes shock, inflammation, fever, some bacterial species deviate from the typical neg. The physical action of washing and rinsing hands removes the spores. Organization of genetic material in bacteria: chromosome in all bacteria repository of all the genes that make up cell, circular double-stranded dnaa highly folded (supercoiled) Lots of: can be spontaneous random errors introduced uring dna. Antibiotic resistance genes: mutation - a physical change in dna sequence, which gives rise to a change. Genetic diversity 3 ways mutations need to occur before significant changes are seen: can be induced - external agents (chemicals, radiation, etc) that distort the physical structure of dna and cause dna-replication enzymes to make mistakes replication. Infection of another bacterial cell by the phage carrying dna apart and a small piece of it may become (cid:498)packaged(cid:499) into from the first cell (cid:523)the (cid:498)donor(cid:499)(cid:524) results in the transfer of the. 10c food spoilage: mesophiles opt.
