Make It Stick: Teaching Gene Targeting with Ribbons and Fasteners

Manipulating gene expression is a commonly used tool to study the effect of a single gene or the hierarchy of gene networks in many different biological disciplines. When working with mice, the most commonly used techniques to manipulate genes...

Homologous chromosomes? Exploring human sex chromosomes, sex determination and sex reversal using bioinformatics approaches

Constructing a robust understanding of homologous chromosomes, sex chromosomes, and the particulate nature of genes is a notoriously difficult task for undergraduate biology students. In this lesson, students expand their knowledge of human...

Meiosis: A Play in Three Acts, Starring DNA Sequence

Meiosis is well known for being a sticky topic that appears repeatedly in biology curricula. We observe that a typical undergraduate biology major cannot correctly identify haploid and diploid cells or explain how and why chromosomes pair before...

Integrating Manipulatives and Animations to Visualize Holliday Junctions

The complex molecular architecture of Holliday junctions is often challenging for undergraduate biochemistry students to conceptualize. In particular, they have difficulty translating from two-dimensional, linear representations shown in textbooks...

Meiosis Remodeled: Inclusion of New Parts to Poppit Bead Models Enhances Understanding of Meiosis

A long-standing tradition uses strings of poppit beads of different colors to model meiosis, especially to show how segments of paired homologous chromosomes are recombined. Our use of orthodontic latex bands to model cohesion of sister...

Sequence Similarity: An inquiry based and "under the hood" approach for incorporating molecular sequence alignment in introductory undergraduate biology courses

Introductory bioinformatics exercises often walk students through the use of computational tools, but often provide little understanding of what a computational tool does "under the hood." A solid understanding of how a bioinformatics...

Learning Quantitative Genetics: Investigation of Genetic Control for Cold Stress Response in Plants

Course-embedded undergraduate research experiences (CUREs) for students have been shown to increase students’ understanding of the process of science, affirm their scientific identity, and improve retention in STEM fields. Despite many CUREs...

Using Constructed Response Questions on High-Stakes Assessments in Large Classes With Limited Support

Large lecture courses often rely heavily, and sometimes exclusively, on Multiple Choice (MC) exams to assess student learning. Constructed Response (CR) questions, in which students generate their own answers, can provide more insight into student...

A CURE-based approach to teaching genomics using mitochondrial genomes

There is an abundance (currently over 1016 DNA bases) of publicly available genetic sequence data and a dearth of trained genomicists to process and interpret it, necessitating more trained bioinformaticians with biological expertise. For...

Student-Generated Analogies for Learning about Information Flow

Using analogies is a standard practice for both teaching and communicating ideas in science. Here we upend the traditional lesson, where the instructor provides a fully constructed analogy and explains it, by having the students develop a complex...
