Size Exclusion Chromatography: An Experiment for High School and Community College Chemistry and Biotechnology Laboratory Programs Linda S. Brunauer and Kathryn K. Davis
Describes an experiment in which students use column chromatography to separate and characterize biomolecules, thus expanding their exposure to chromatographic procedures beyond those more commonly employed at the secondary level (e.g., paper or thin-layer chromatography).

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.

A Chemistry Course with a Laboratory for Non-Science Majors Emeric Schultz
A non-science-majors course driven by the project-focused lab agenda. Lecture topics follow an evolutionary story line starting with the Big Bang, through the development of stars and planets to life on earth. The topics of bonding, structure, and interactions are aided by molecular modeling.

Genomics: The Science and Technology Behind the Human Genome Project (by Charles R. Cantor and Cassandra L. Smith) reviewed by Martin J. Serra
This book is an outgrowth of a series of lectures given by one of the former heads (CRC) of the Human Genome Initiative. The book is designed to reach a wide audience, from biologists with little chemical or physical science background through engineers, computer scientists, and physicists with little current exposure to the chemical or biological principles of genetics.

Immobilized Lactase in the Biochemistry Laboratory Matthew J. Allison and C. Larry Bering
Lactase from over-the-counter tablets for patients with lactose intolerance is immobilized in polyacrylamide, which is then milled into small beads and placed into a chromatography column. A lactose solution is added to the column and the eluant is assayed using the glucose oxidase assay, available as a kit.

Three Programs for DOS: Abstract of Volume 10B, Number 1 1. DNA Sequencing John F. Beck and David L. Bunbury
DNA Sequencing is a package of five programs that instructs and tests students on the Maxam-Gilbert method of sequencing DNA. It can be used as a self-instruction unit, as an assignment, and as a testing vehicle. The package is aimed at a university level chemistry, biochemistry, or chemical-biology course, but advanced senior high school students will also find it useful.
