Abstract

This activity, which allows students to extract DNA from plant and animal cells, serves as a spectacular example of the complexity of biochemical structure and function and fits well with a discussion of nucleic acids, hydrogen bonding, genetic coding, and heredity. DNA extraction can also be used in conjunction with a discussion of polymers and their properties. This activity can be used to complement a diffraction experiment illustrating how the double helix structure of DNA was determined.

  Basic principles of enzyme kinetics are demonstrated using the enzyme glucose oxidase. The glucose oxidase enzymatic reaction is coupled to horseradish peroxidase, which in turn catalyzes the oxidation of a dye to a bright blue-green color. The appearance ...
