JCE Classroom Activity
Liver and Onions: DNA Extraction from Animal and Plant Tissues
Karen J. Nordell, Anne-Marie L. Jackelen, S. Michael Condren, George C. Lisensky, and Arthur B. Ellis
University of Wisconsin-Madison, Department of Chemistry, Madison, WI 53706-1396
Cover
March 1999
Vol. 76 No. 3
p. 400A
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.
