Recommends utilizing biochemistry problems to develop students' abilities to clearly identify the relevant questions hidden in problematic situations and to select the information required to solve them. This procedure is highly motivating and offers students a tool for evaluating their achievements. (Author/CCM)

Examines the responses of senior academic biochemists to an incident of scientific wrongdoing. Concludes that these individuals endorsed less-formal action when either the actions were believed to have the potential to publicly embarrass the offending individual, or when the actions might adversely affect the professional career of the…

Describes the use of a theoretical framework of DNA topology and a simple method for modeling structures as successful ways of teaching students about DNA supercoiling. (WRM)

Presents an experiment aimed at constructing a genomic library that can be carried out over a week. Helps students learn concepts such as donor and vector DNAs, construction of recombinant DNA, host strain, and experiments in gene cloning more clearly. (PVD)

Demonstrates how leaf slices provide an inexpensive material for illustrating several fundamental points about the biochemistry of photosynthesis and respiration. Presents experiments that illustrate the effects of photon flux density and herbicides and carbon dioxide concentration. (DDR)

Describes a science laboratory experiment on odors which demonstrates the integration of chemistry and biology. Explains how the smell function works. (Contains 13 references.) (YDS)

Examines the biological factors underlying autism, focusing on research in four areas: (1) neurological abnormalities; (2) biochemical abnormalities; (3) genetic problems; and (4) problems during pregnancy or birth. Maintains that autism is a heterogeneous disorder and that there is no unified model that explains its etiology. (Author/KB)

Presents methods that can be used to isolate the enzyme tyrosinase and to assay its activity. Lists instructions for a laboratory activity that has variable but frequently dramatic results. (WRM)

Uses panels taken from manga, Japanese comics and cartoons, to supplement explanations of biochemical terms and topics in biochemistry classes. Results indicate that the use of manga helped students remember what they had learned. (Author/CCM)

Girls' time in sex-typed leisure activities was studied across 2 years in middle childhood (n=98, M=8.2 years in Year 1), early adolescence (n=106, M=11.7 years), and middle adolescence (n=86, M=14.9 years). In annual home interviews, White middle-class girls, mothers, and fathers rated their gendered attitudes, interests, and personality…

The average biotech catalog contains a dizzying array of kits offering tried-and-true protocols in molecular biology and biochemistry. Prepackaged experiences, ranging from DNA fingerprinting to protein purification, are now available to high school students. Although commercial kits designed for education provide excellent hands-on experiences in…

The present research describes an efficient procedure to obtain high levels of trypsinogen and chymotrypsinogen by using a simple, rapid, and easily reproducible method. The extraction process and the time-course of activation of zymogens can be carried out in a single laboratory period, without sophisticated equipment. The main objective was to…

This article describes the use of poster preparation and display as an assessment tool and includes feedback from the students and academics concerned. This alternative approach has been used for four years since 2000 for biological science students studying biochemistry. The object of this approach was to get away from traditional teaching…

Internet-based distance education seems to be an attractive alternative to offer courses dealing with specific topics that are not conveniently explored in undergraduate courses. This is a good way to provide access to the recent and updated discoveries in this research area and to reach people who could not take the classes in the traditional…

Bioinformatics has emerged as an important research tool in recent years. The ability to mine large databases for relevant information has become increasingly central to many different aspects of biochemistry and molecular biology. It is important that undergraduates be introduced to the available information and methodologies. We present a…
