Abreu, Paula Alvarez; Carvalho, Karina de Lima; Rabelo, Vitor Won-Held; Castro, Helena Carla – Biochemistry and Molecular Biology Education, 2019
Computational techniques have great potential to improve the teaching-learning. In this work, we used a computational strategy to visualize three-dimensional (3D) structures of proteins and DNA and help the student to comprehend biochemistry concepts such as protein structure and function, substrate, and inhibitors as well as DNA structural…

Ochs, Raymond – Biochemistry and Molecular Biology Education, 2019
Understanding redox reactions in biochemistry requires a clear grasp of three definitions: electron exchange, oxidation number, and oxygen atom insertion. Here, the electrochemical cell is explained for redox-active ions, introducing a new comparison between the measurement of midpoint potential and the measurement of initial velocity for enzymes.…

Jiao, Li; Xueli, Li; Xiujuan, Shi; Song, Jia; Jie, Xu; Lixia, Lv; Wenzhuo, Yang; Lei, Xu – Biochemistry and Molecular Biology Education, 2019
For medical students, we combine the laboratory practice with clinical applications by developing biochemical and molecular biology experiments. In this experiment, students first collect their own buccal epithelial cells by a noninvasive mouthwash method. Then, they extract genomic DNA and perform polymerase chain reaction (PCR) to amplify…

Carrasco, Gonzalo A.; Behling, Kathryn C.; Lopez, Osvaldo J. – Biochemistry and Molecular Biology Education, 2019
We developed a hands-on course in molecular biology for undergraduate underrepresented in medicine (URM) students. To incentivize student preparation for team-based learning (TBL) activities, we implemented a novel grading schema that requires a minimum individual readiness assurance test (iRAT) score to share the team group readiness assurance…

Pieczynski, Jay N.; Deets, Amber; McDuffee, Alexis; Lynn Kee, H. – Biochemistry and Molecular Biology Education, 2019
Undergraduates learn that gene editing in diverse organisms is now possible. How targeted manipulation of genes and genomes is utilized in basic science and biomedicine to address biological questions is challenging for undergraduates to conceptualize. Thus, we developed a lab experience that would allow students to be actively engaged in the full…

Militello, Kevin T.; Reinhardt, Josephine A. – Biochemistry and Molecular Biology Education, 2019
Next generation sequencing has revolutionized molecular biology and has provided a mechanism for rapid DNA and RNA sequence analysis. Yet, there are few resources to introduce next generation sequencing into the undergraduate biochemistry and molecular biology curriculum. Herein, we describe the design, execution, and assessment of a four-week…

Howell, Michelle E.; Booth, Christine S.; Sikich, Sharmin M.; Helikar, Tomáš; Roston, Rebecca L.; Couch, Brian A.; Dijk, Karin – Biochemistry and Molecular Biology Education, 2019
Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure-function relationships, such models have not been widely implemented in biochemistry classrooms.…

Hammerstad, Marta; Røhr, Åsmund K.; Hersleth, Hans-Petter – Biochemistry and Molecular Biology Education, 2019
Many laboratory courses consist of short and seemingly unconnected individual laboratory exercises. To increase the course consistency, relevance, and student engagement, we have developed a research-inspired and project-based module, "From Gene to Structure and Function". This 2.5-week full-day biochemistry and structural biology module…

de Vries, Lisbeth Elvira; May, Michael – Biochemistry and Molecular Biology Education, 2019
This study presents an evaluation of virtual laboratory simulation for educational use in the "AP Degree Programme in Chemical and Biotechnical Science at University College Copenhagen" in Denmark. The purpose was to test if, and how, virtual laboratory simulation could be applied to a practically oriented education such as the education…

Deutch, Charles E. – Biochemistry and Molecular Biology Education, 2018
Many fruits and vegetables undergo browning when they are cut and the tissue is exposed to the air. This is due to the activity of the enzyme polyphenol oxidase (PPO, EC 1.14.18.1) with endogenous substrates. In this laboratory experiment, students prepare slices of different varieties of apples and assess the rate of browning. They make a simple…

Yeo, Brandon Pei Hui; Foong, Lian Chee; Tam, Sheh May; Lee, Vivian; Hwang, Siaw San – Biochemistry and Molecular Biology Education, 2018
Structures and functions of protein motifs are widely included in many biology-based course syllabi. However, little emphasis is placed to link this knowledge to applications in biotechnology to enhance the learning experience. Here, the conserved motifs of nucleotide binding site-leucine rich repeats (NBS-LRR) proteins, successfully used for the…

Heineman, Richard H. – Biochemistry and Molecular Biology Education, 2018
These three biology songs can be used for educational purposes to teach about biochemical concepts. They touch on three different topics: (1) cancer progression and germ cells, (2) gene expression, promoters, and repressors, and (3) electronegativity and the biochemical basis of photosynthesis.

Shen, Jie; Zhu, Xiang; Jin, Kai; Li, Ya; Gu, YiTian; Huang, Jiahong; Qu, Yulan; Li, Xiaoyu – Biochemistry and Molecular Biology Education, 2018
The development and evaluation of a 6-hours laboratory class, based on capillary electrophoresis (CE) and the detection of microbial contaminants, is described. It can be easily scaled up or down, to suit class sizes up to 188 and completed in a shorter time scale. CE uses narrow-bore fused-silica capillaries to separate a complex array of large…

Zhang, Nianhui; Yu, Dong; Zhu, Xiaofeng – Biochemistry and Molecular Biology Education, 2018
The practice of RNA isolation in undergraduate experimental courses is rare because of the existence of robust, ubiquitous and stable ribonucleases. We reported here modifications to our original protocol for RNA isolation from plant tissues, including the recovery of nucleic acids by ethanol precipitation at 0 degrees C for 10 min and the…

Lawton, Jeffrey A.; Prescott, Noelle A.; Lawton, Ping X. – Biochemistry and Molecular Biology Education, 2018
We have developed an integrated, project-oriented curriculum for undergraduate molecular biology and biochemistry laboratory courses spanning two semesters that is organized around the "ldhA" gene from the yogurt-fermenting bacterium "Lactobacillus bulgaricus," which encodes the enzyme d-lactate dehydrogenase. The molecular…
