BIOL 1202 : BIO 1202 EXAM 2
Document Summary
Bacteria: cell wall = semi-rigid, permeable, made of peptidoglycan (carbohydrate with amino acids attached). Gives bacteria shapes. (shapes are determined by the geno of that bacteria) September 19, 2014: sex pilis is the red line (acts to pull the cells together, conjugatin have the ability to transform dna. Prokaryotes: cell wall, shapes: bacilli, cocci, spirilla, capsules and slime layers, pili, rotating flagella (movement, endospore = protective resting structures, bacteria surround by durable cell wall. It"s much more harder to separate at these high: at has two hydrogen bond, and gc has three hydrogen bounds holding them together. Have a greater gc type in their geno, and more: high salt extreme salt (halophiles) , and hollowphiles low salt, extreme halophiles temperature. their geno. Chew up toxic waste: exxon-valdz oil spill. Super bacterium : endospores can survive these environments, extremely resillant to dna damage, can repare their dna without single error, build back its genome.
