Two Hypercard calculators for molecular biology.
Two calculators built in Macintosh Hypercard are described. GelFragSizer estimates and plots DNA restriction fragment sizes, using the local reciprocal or cubic spline methods. Enzyme Kinetics estimates the Michaelis-Menton rate parameters for enzyme-catalyzed reactions, and plots data versus estimated curve in a variety of formats. These stacks help to demonstrate the ease and sophistication of calculation tools that scientists can develop with Hypercard.
