Kudish, Philip; Schlag, Erin; Kaplinsky, Nicholas J. – Bioscene: Journal of College Biology Teaching, 2015
We developed a multi-week laboratory in which college-level introductory biology students investigate Mendel's stem length phenotype in peas. Students collect, analyze and interpret convergent evidence from molecular and physiological techniques. In weeks 1 and 2, students treat control and experimental plants with Gibberellic Acid (GA) to…

RNase One Gene Isolation, Expression, and Affinity Purification Models Research Experimental Progression and Culminates with Guided Inquiry-Based Experiments
Peer reviewed Peer reviewed
Direct linkDirect link
Bailey, Cheryl P. – Biochemistry and Molecular Biology Education, 2009
This new biochemistry laboratory course moves through a progression of experiments that generates a platform for guided inquiry-based experiments. RNase One gene is isolated from prokaryotic genomic DNA, expressed as a tagged protein, affinity purified, and tested for activity and substrate specificity. Student pairs present detailed explanations…

Middle School Students' Learning about Genetic Inheritance through On-Line Scaffolding Supports
Direct linkDirect link
Manokore, Viola – ProQuest LLC, 2010
The main goal of school science is to enable learners to become scientifically literate through their participation in scientific discourses (McNeill & Krajcik, 2009). One of the key elements of scientific discourses is the ability to construct scientific explanations that consist of valid claims supported by appropriate evidence (e.g., McNeill &…

An Hypothesis-Driven, Molecular Phylogenetics Exercise for College Biology Students
Peer reviewed Peer reviewed

Parker, Joel D.; Ziemba, Robert E.; Cahan, Sara Helms; Rissing, Steven W. – Biochemistry and Molecular Biology Education, 2004
This hypothesis-driven laboratory exercise teaches how DNA evidence can be used to investigate an organism's evolutionary history while providing practical modeling of the fundamental processes of gene transcription and translation. We used an inquiry-based approach to construct a laboratory around a nontrivial, open-ended evolutionary question…

An Inquiry into Protein Structure and Genetic Disease: Introducing Undergraduates to Bioinformatics in a Large Introductory Course
Peer reviewed Peer reviewed
Direct linkDirect link
Bednarski, April E.; Elgin, Sarah C. R.; Pakrasi, Himadri B. – Cell Biology Education, 2005
This inquiry-based lab is designed around genetic diseases with a focus on protein structure and function. To allow students to work on their own investigatory projects, 10 projects on 10 different proteins were developed. Students are grouped in sections of 20 and work in pairs on each of the projects. To begin their investigation, students are…
