Enzymes are organic molecules known for their catalytic nature because they accelerate metabolic reactions in organisms. The study of enzyme functions and modes of action is essential to understand Biochemistry. This study aimed to analyse the acetylcholinesterase enzymatic activity, as well as the enzymatic inhibition mechanism in practical…

Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of…

Human ageing and age-associated diseases are among the greatest challenges and financial burdens faced by developed countries. Unfortunately, undergraduate students often do not experience any laboratory training in ageing research in the current laboratory curriculum of majors in biology, biotechnology, or medicine. In this study, we developed…

"Sinorhizobium meliloti" is a bacterium of great agroeconomic importance because of its ability to fix atmospheric nitrogen in symbiotic association with alfalfa ("Medicago sativa") roots, and it is often used in model studies. We investigated the effects of exopolysaccharides (EPSs) in cell-to-cell and cell-to-surface…

In this study, firstly, university biology students' conceptual understanding and potential misconceptions concerning meiosis were studied. Secondly, an easily applicable drawing task was used to foster students' metaconceptual awareness which would help them to reach conceptual change. A quasi-experimental design with a non-equivalent control…

Contemporary research suggests an urgent need for educators to improve the quality of STEM teaching and learning. We developed a semester-long model curriculum for STEM teaching and learning. The overarching goal of this study was to establish an authentic inquiry approach to advanced laboratory courses that is interdisciplinary, collaborative,…

Mutation, diversity, natural selection and the biology of human pathogens (including antibiotic resistance) are key features of the biosciences curriculum at A Level and undergraduate study. Few resources exist to allow students to engage with these topics in an interactive manner. This paper describes an interactive, online simulation of mutation…

All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and, consequently, it contains a particular set of proteins that determine its function. Here, we describe a laboratory exercise addressed to undergraduate students that aims to…

Undergraduate biology majors require biological literacy about the critical and dynamic relationships between plants and ecosystems and the effect human-made processes have on these systems. To support students in understanding systems relationships, we redesigned an undergraduate botany course using an ecological framework and embedded systems…

Lists 15 commonly encountered misconceptions/misunderstandings in biology, together with specific suggestions to help teachers and textbook authors clarify each misconception. Included are problems related to understanding differences between acellular and multicellular, respiration and photosynthesis, egestion and excretion, and homeostasis and…

Flow-diagrams, algorithms, decision logic tables, and concept maps are presented in detail as methods for teaching practical procedures, problem solving, and basic concepts in microbial genetics. It is suggested that the flexible use of these methods should lead to an improved understanding of microbial genetics. (Author/MA)

The concepts of "animal" held by some New Zealand primary, secondary, and college students were explored, using both an interview (N=39) and multiple-choice survey (N=150) approach. The results indicate that many students of all ages have a restricted concept of "animal" compared with that of a biologist. (Author/DC)

Examined are some of the distinctive features of the biological sciences. Discussed are the use of models with case studies, universal principles, and alternative frameworks. (CW)
