X-ray Diffraction and the Discovery of the Structure of DNA  David T. Crouse
Describes a step-by-step method of teaching the X-ray diffraction analysis of DNA using the approach employed by Watson, Crick, Wilkins, Franklin, and Gosling. Excerpts of their original articles describe the obstacles encountered by these researchers, the contributions made by each, and the degree to which X-ray diffraction aided their determination of DNA's structure.

Testing for Genetically Modified Foods Using PCR  Ann Taylor and Samin Sajan
The polymerase chain reaction (PCR) is a powerful technique used to detect and amplify a specific DNA sequence. In this experiment, DNA is isolated from commercially available corn meal and corn-muffin mixes, then a sequence unique to transgenic plants is amplified by PCR. The amplified sequence is identified by its size (192 base pairs) by agarose gel electrophoresis. This experiment could be used in either a biochemistry course or in an analytical chemistry course in a curriculum that integrates biochemistry throughout the course work.

An Attack on the AIDS Virus: Inhibition of the HIV-1 Protease. New Drug Development Based on the Structure and Activity of the Protease and its Role in the Replication and Maturation of the Virus  Volker, Eugene J.
Article shows how research into the biochemistry of HIV may lead to a method for controlling its growth and maturation. This research illustrates some basic enzyme chemistry and holds student appeal due to the tie into current affairs.

Separation of glycohemoglobins by ion exchange chromatography: An undergraduate biochemistry laboratory experiment  Jackman, Lance E.
In this experiment, students determine the glycohemoglobin level of whole blood samples by separation of the glycohemoglobins from the nonglycosylated hemoglobins using cation exchange chromatography.
