Abstract

The primary objectives of these laboratory exercises are to familiarize advanced undergraduate and graduate students (and instructors) with the general concepts, techniques, and uses of DNA fingerprinting and to remove some of the perceived mystique underlying molecular genetics. The technique of DNA amplification fingerprinting (DAF) is partitioned into four independent laboratory exercises that include DNA isolation, DNA amplification, gel electrophoresis and silver staining, and data collection and analysis. Although the DNA amplification and gel electrophoresis exercises are emphasized, very detailed and easy-to-follow instructions and protocols are provided for all aspects of the DNA fingerprinting process. These exercises, or similar ones, have been successfully completed on the first attempt by several classes of novice graduate students and other researchers.
