title: Two Hypercard calculators for molecular biology.
abstract: 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.
