Observation of DNA Molecules Using Fluorescence Microscopy and Atomic Force Microscopy Takashi Ito
Describes procedures for an instrumental analysis laboratory to observe individual double-stranded DNA (dsDNA) molecules using fluorescence and atomic force microscopy; immobilization of dsDNA molecules on a planar substrate in their stretched form permits students to measure the size of the dsDNA molecules using these microscopic techniques.

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.

DNA Profiling of the D1S80 Locus: A Forensic Analysis for the Undergraduate Biochemistry Laboratory D. Dewaine Jackson, Chad S. Abbey, and Dylan Nugent
Describes a laboratory exercise in DNA profiling that can be used to demonstrate four fundamental procedures: isolation of genomic DNA from human cells, use of the polymerase chain reaction to amplify DNA, separation of amplified DNAs on agarose and polyacrylamide gels, and quantitative analysis of data (while comparing two different gel separation techniques).

Glycosyltransferases A and B: Four Critical Amino Acids Determine Blood Type Natisha L. Rose, Monica M. Palcic, and Stephen V. Evans
Human A, B, and O blood type is determined by the presence or absence of distinct carbohydrate structures on red blood cells. In this review the chemistry of the blood group ABO system and the role of glycosyltransferase A, glycosyltransferase B, and the four amino acids critical to determining blood group status are discussed.

Organic Chemistry of the Cell: An Interdisciplinary Approach To Learning with a Focus on Reading, Analyzing, and Critiquing Primary Literature Craig A. Almeida and Louis J. Liotta
Describes a sophomore-level learning community entitled Organic Chemistry of the Cell comprised of two linked courses, Organic Chemistry I and Cell Biology, and an Integrative Seminar. The Integrative Seminar is grounded in the reading, critical analysis, and discussion of primary literature that ties together organic chemistry and cell biology.

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.

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*
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.
