01 Source of DNA Base Percentage Adenine Guanine Cytosine Thymine Sca urchin 32.8 17.7 17.3 32.1 Salmon 29.7 20.8 20.4 29.1 Wheat 28.1 21.8 22.7 E; coli 24.7 26.0 Human 30.4 29.0 a) Explain how the sea urchin and salmon data demonstrate both of Chargaff's rules Using Chargaff's rules, fill in the table with your predictions of the missing percentages of bases starting with the wheat genome and proceeding through coli, human; and ox. Show how you arrived at your answers_ c) If Chargaff's rule-that the amount of A equals the amount of T and the amount of C equals the amount of G ~is valid, then hypothetically we could extrapolate this to the combined DNA of all species on Earth (like one huge Earth genome) . To see whether the data in the table support this hypothesis, calculate the average percentage for each base in your completed table by averaging the values in each column: Does Chargaff's equivalence rule still hold true?
