Document Summary
Major themes: heritable info continuity of life; info expressed/regulated w/o loss of content; imperfect/flawed info transfer variations. Bottom line: prokaryotes cellular fission 2 equivalent daughter cells. Very conserved (similar dna polymerase molecules in all species) Millions of tubular e. coli cells grown at 37 c. Harvested and calculated volumes of each (using formula of a cylinder): Even though same genotype, they did not all have the same volume. They had different phenotypes. (average volume: 0. 83 m 3 ) Independent variable = the variable manipulated by the investigator. Dependent variable = measured in response to the independent variable. Grown initially in different temperatures (25 c vs 30 c) different rates of growth. Taken and moved to 37 c environment similar rates of growth. Integrating questions: the shape of the graph is slightly more complex than a symmetrical bump. The flask of bacteria grown initially in 30 c is growing faster.
