Encouraging Meaningful Learning
The July 2015 issue of the Journal of Chemical Education is now available online to subscribers. This issue includes articles on summer book recommendations; biochemistry; web-based learning; assessment; organic chemistry; physical chemistry; carbon footprint activities.
In But You Have the Whole Summer Off, Right?, Norbert J. Pienta muses that managing expectations about serving academic roles may be more important than ever.
Food for Thought, Starting with Cheese ~Cheryl Baldwin Frech; Stories, Style, and a Few Study Breaks ~ Brian P. Coppola; What If?; The Lifecycle of Software Objects; Sapiens: A Brief History of Humankind; and Gulp: Adventures on the Alimentary Canal ~ Brittland DeKorver; Mathematical Insights, the Seventh Flavia de Luce Novel, and Scientific Ideas We May Be Able To Give Up ~ Hal H. Harris
On the Cover
In Detection of the cp4 epsps Gene in Maize Line NK603 and Comparison of Related Protein Structures: An Advanced Undergraduate Experiment, Nicole K. Swope, Patrick J. Fryfogle, and Tami L. Sivy describe a flexible, rigorous laboratory experiment for upper-level biochemistry undergraduates. In this experiment, DNA is extracted and purified from maize kernel and leaf samples collected from field samples of maize with a glyphosate-resistant transferase gene. Students detect the transgene of this genetically modified crop and assess the structural characteristics of the protein translated from the gene of interest using a combination of bioinformatics and computational-modeling techniques.
