A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images Amand A. Lucas This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically. Lucas, Amand A. J. Chem. Educ. 2008, 85, 737.

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. Taylor, Ann; Sajan, Samin.

A 3D Model of Double-Helical DNA Showing Variable Chemical Details Susan G. Cady A 3D double-helical DNA model, made by placing beads on a wire and stringing beads through holes in plastic canvas, is described. Suggestions are given to enhance the basic helical frame to show the shapes and sizes of the nitrogenous base rings, 3' and 5' chain termini, and base pair hydrogen bonding. Students can incorporate random or real gene sequence data into their models. Cady, Susan G. J. Chem. Educ. 2005, 82, 79.

Does Active Learning through an Antisense Jigsaw Make Sense? Mahadevan Seetharaman and Karin Musier-Forsyth Three journal articles on nucleic acid antisense modification strategies were assigned to 12 students as part of an active learning "jigsaw" exercise for a graduate-level chemistry course on nucleic acids. The effectiveness of this active learning strategy and its applicability to other topics are discussed in this article. Seetharaman, Mahadevan; Musier-Forsyth, Karin. J. Chem. Educ. 2003, 80, 1404.

Analysis of DAPI and SYBR Green I as Alternatives to Ethidium Bromide for Nucleic Acid Staining in Agarose Gel Electrophoresis Kevin M. Bourzac, Lori J. LaVine, and Margaret S. Rice DAPI and SYBR Green I are good staining alternatives to ethidium bromide in that they have similar sensitivity and are both easy to use. SYBR Green I is more expensive than EB or DAPI; however, the limited safety data suggest that SYBR Green I is the safest stain. Bourzac, Kevin M.; LaVine, Lori J.; Rice, Margaret S. J. Chem.

Allele-Specific Polymerase Chain Reaction-Based Genotyping of a Normal Variation in Human Color Vision Beth Wilson, Ira M. Lubin, and Kathryn B. Grant Students utilize microcentrifugation and silica-gel column chromatography to extract DNA from their own buccal (cheek) epithelial cells. The polymerase chain reaction and agarose gel electrophoresis are then employed to identify a single nucleotide polymorphism that is responsible for a commonly encountered variation in human red color vision.

Revealing the Backbone Structure of B-DNA from Laser Optical Simulations of Its X-ray Diffraction Diagram A. A. Lucas, Ph. Lambin, R. Mairesse, and M. Mathot A visible laser and a set of nine specially designed diffraction gratings held on a single slide have been used to build up progressively a classroom optical simulation of the diffraction of X-rays by a B-DNA fiber. The nine optical transforms allow understanding, without recourse to helical diffraction theory, of how the prominent features of the observed diffraction pattern arise from each of the structural parameters of the DNA backbone.
