The relationship of free energy change (?G) to the concentrations of reactants and products is important because it predicts the direction of spontaneous chemical reactions. Familiarity with this relationship is essential for understanding energy conversions in cells. Consider for example the hydrolysis of ATP to ADP and inorganic phosphate (Pi): […]

A student performed a BioRad miniprep of plasmid DNA that resulted in 100ul(microliter) of DNA solution. To determine the concentration of this solution, 20ul of the DNA solution was placed in 480ul of water and the absorbance of the diluted sample was measured at 260nm. The absorbance relative to a […]
