It has been shown that active learning strategies are effective in teaching complex STEM concepts. In this study, we developed and implemented a laboratory experiment for teaching the concepts of Boolean logic gates, molecular beacon probes, molecular computing, DNA logic gates, microRNA, and molecular diagnosis of hepatocellular carcinoma, which…

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.…

Takor, Gaius; Morgan, Christopher E.; Chiu, Liang-Yuan; Kendrick, Nashea; Clark, Emily; Jaiswal, Rohan; Tolbert, Blanton S. – Journal of Chemical Education, 2020
Two-dimensional nuclear magnetic resonance (2D NMR) techniques are regularly used for the determination of RNA structures. In an effort to introduce advanced level students who are generally not acquainted with or exposed to these techniques, this work, which has been designed as a practicum, utilizes a combination of 2D NMR techniques to help…

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…

Sun, Ji-Zheng; Tang, Yu-Jing; Sa, Rong-Bo; Gao, Yan-Xia – Journal of Chemical Education, 2019
A bioinformatics laboratory experiment was designed to help undergraduate students learn RNA structure and function in biochemistry courses. In this laboratory experiment, students used 5S rRNAs as material to predict secondary structure and visualize three-dimensional (3D) structure. Students first downloaded molecular information from the 5S…

Bussey, Thomas J.; Orgill, MaryKay – Chemistry Education Research and Practice, 2019
Instructors draw on their intentions for student learning in the enactment of curriculum, particularly in the selection and presentation of external representation of scientific phenomena. These representations both create opportunities for students to experience non-experiential biochemical phenomena, such as protein translation, and constrain…
