Teaching Molecular Phylogenetics through Investigating a Real-World Phylogenetic Problem
Peer reviewed Peer reviewed
Direct linkDirect link
Zhang, Xiaorong – Journal of Biological Education, 2012
A phylogenetics exercise is incorporated into the "Introduction to biocomputing" course, a junior-level course at Savannah State University. This exercise is designed to help students learn important concepts and practical skills in molecular phylogenetics through solving a real-world problem. In this application, students are required to identify…

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 &…

Chang, Ming-Mei; DiGennaro, Peter; Macula, Anthony – Biochemistry and Molecular Biology Education, 2009
Plants defend themselves against pathogens via the expressions of disease resistance (R) genes. Many plant R gene products contain the characteristic nucleotide-binding site (NBS) and leucine-rich repeat (LRR) domains. There are highly conserved motifs within the NBS domain which could be targeted for polymerase chain reaction (PCR) cloning of R…

Porter, Sandra G.; Day, Joseph; McCarty, Richard E.; Shearn, Allen; Shingles, Richard; Fletcher, Linnea; Murphy, Stephanie; Pearlman, Rebecca – CBE - Life Sciences Education, 2007
Researchers in the field of bioinformatics have developed a number of analytical programs and databases that are increasingly important for advancing biological research. Because bioinformatics programs are used to analyze, visualize, and/or compare biological data, it is likely that the use of these programs will have a positive impact on biology…

Centeno, Nuria B.; Villa-Freixa, Jordi; Oliva, Baldomero – Biochemistry and Molecular Biology Education, 2003
Understanding the basic principles of structural biology is becoming a major subject of study in most undergraduate level programs in biology. In the genomic and proteomic age, it is becoming indispensable for biology students to master concepts related to the sequence and structure of proteins in order to develop skills that may be useful in a…

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…
