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.

Testing for Ultraviolet Toxicity Using Fungi Marcelo Vital and Patricia Esperón
In this article, we describe a laboratory project quantifying the effects of UV radiation on a suspension of living cells. This laboratory experiment was designed for undergraduate students in biochemistry. The experiment was carried out employing different fungi strains, changing the dosage of radiation, the distance to the UV source, and the exposure period to the UV radiation. The quantity of viable spores was calculated and the doseresponse curves were drawn. Students were able to prove that 100% of mortality was achieved with the longest time of exposure.

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.
