BIOL 2153 : Exam 1 DNA Notes W Book Notes In Blue
Document Summary
Short life cycle: produce a lot of offspring, has genetic variation. Saccharomyces cerevisiae, drosophilia melanogaster, nematode worm, mustard weed, mice, humans: types of research, 1 - basic, exp. Involved in photosynthesis: have separate dna, encode for proteins that fxn in chloroplast only & make components of chloroplast protein synthesis equipment, prokaryotes, no nuclear envelope --> cell wall & cell membrane, divided into bacteria & archaea, bact. Found in water, soil, hot springs, salt marshes, ocean depths --> bacteria cannot: dna, has o, p, c, n (in the bases, p found in the back bone. Frederick griffith transformation experiment: mice injected w/rough strep don"t die, mice injected w/ smooth strep die, heated smooth strep + rough strep = transformation. If a iis --> r, r --> iis only, not iiis: bact"l mutations type-specific, mice injected w, r --> lived, s --> died, heat killed s --> lived.
