In pea plants flower position, stem length, and seed shape are controlled by independently assorting genes. Each characteristic has the following mode of inheritance: Character Dominant RecessiveFlower position Axial (A) Terminal (a)Stem length Tall (T) Dwarf (t)Seed shape Round (R) Wrinkled (r) If a plant that is heterozygous for all […]

A type of phosphatase can be assayed using p-nitrophenyl phosphate but the assay is performed at pH 7.8, which is the optimum for this enzyme. The initial velocity measured at the highest substrate concentration was .45 deltaA_400 / minute. Convert this velocity to a change in concentration/minute (microM/minute). HINT Use […]

The Meselson-Stahl experiments were groundbreaking studies in molecular biology. Some of the clarity of the centrifugation results was due to the that the DNA was fragmented during handling (although the experimenters did not know it at the time). As quoted in Davis, Stahl said that pipetting DNA was like “throwing […]
