Wise, Michael J. – Bioscene: Journal of College Biology Teaching, 2018
As a foundational evolutionary concept, the Hardy-Weinberg principle should be taught enthusiastically in introductory biology courses. In a companion Perspectives paper, I made the case that students are often given limited or incorrect information on the HW principle due to a lack of mastery or confidence on the part of their teachers. The…

Wise, Michael J. – Bioscene: Journal of College Biology Teaching, 2018
The Hardy-Weinberg principle (HWP) is a fundamental model upon which much of the discipline of population genetics is based. Despite its significance, students often leave introductory biology courses with only a shallow understanding of the use and implications of the HWP. I contend that this deficiency in student comprehension is too-often a…

Peterson, Elizabeth K.; Carrico, Pauline – Bioscene: Journal of College Biology Teaching, 2015
In this paper, we describe a two-week learning module where students tested the role of the "fruitless" gene on aggression and courtship in "Drosophila melanogaster" via team-based learning (TBL) strategies. The purpose of this module was to determine if TBL could be used in the future as a platform to implement the course…

Planchard, Matthew; Daniel, Kristy L.; Maroo, Jill; Mishra, Chandrani; McLean, Tim – Bioscene: Journal of College Biology Teaching, 2015
We conducted a mixed methods study in an upper-level genetics course exploring the relationships between student motivation, homework completion, and academic achievement at the college level. We used data from an open-ended questionnaire, homework grades and completion reports, and exam scores. We used these data sources to measure self-perceived…

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…

Nogaj, Luiza A. – Bioscene: Journal of College Biology Teaching, 2014
A nine-week laboratory project designed for a sophomore level molecular biology course is described. Small groups of students (3-4 per group) choose a tumor suppressor gene (TSG) or an oncogene for this project. Each group researches the role of their TSG/oncogene from primary literature articles and uses bioinformatics engines to find the gene…

Roy, Nicole M. – Bioscene: Journal of College Biology Teaching, 2013
RNA interference (RNAi) is a powerful technology used to knock down genes in basic research and medicine. In 2006 RNAi technology using "Caenorhabditis elegans" ("C. elegans") was awarded the Nobel Prize in medicine and thus students graduating in the biological sciences should have experience with this technology. However,…

Shultz, Jeff – Bioscene: Journal of College Biology Teaching, 2011
I have devised a method with which a molecular size standard can be readily manufactured using Lambda DNA and PCR. This method allows the production of specific sized DNA fragments and is easily performed in a standard molecular biology laboratory. The material required to create these markers can also be used to provide a highly robust and…

Shumate, Alice M.; Windsor, Aaron J. – Bioscene: Journal of College Biology Teaching, 2010
The increase in publications presenting molecular evolutionary analyses and the availability of comparative sequence data through resources such as NCBI's GenBank underscore the necessity of providing undergraduates with hands-on sequence analysis skills in an evolutionary context. This need is particularly acute given that students have been…

Palsule, Vrushalee; Coric, Dijana; Delancy, Russell; Dunham, Heather; Melancon, Caleb; Thompson, Dennis; Toms, Jamie; White, Ashley; Shultz, Jeffry – Bioscene: Journal of College Biology Teaching, 2010
A clear understanding of basic gene structure is critical when teaching molecular genetics, the central dogma and the biological sciences. We sought to create a gene-based teaching project to improve students' understanding of gene structure and to integrate this into a research project that can be implemented by instructors at the secondary level…

Lassiter, Christopher S. – Bioscene: Journal of College Biology Teaching, 2010
Monohybrid crosses are taught in biology labs across the country using peas and corn. Students studying monohybrid crosses using zebrafish ("Danio rerio") would encounter a new model organism, and those interested in human or veterinary medicine would have increased interest. To this end, our college has implemented a laboratory exercise at the…

Sato, Takumi; Phillips, Bonnie; Latourelle, Sandra M.; Elwess, Nancy L. – Bioscene: Journal of College Biology Teaching, 2010
The 14-base pair hypervariable region in mitochondrial DNA (mtDNA) of Asian populations, specifically Japanese and Chinese students at Plattsburgh State University, was examined. Previous research on this 14-base pair region showed it to be susceptible to mutations and as a result indicated direct correlation with specific ethnic populations.…

Keyes, Carol A.; Subramanian, Senthil; Yu, Oliver – Bioscene: Journal of College Biology Teaching, 2009
Hairy root transformation has been widely adapted in plant laboratories to rapidly generate transgenic roots for biochemical and molecular analysis. We present hairy root transformations as a versatile and adaptable model system for a wide variety of undergraduate laboratory courses and research. This technique is easy, efficient, and fast making…

Pontelli, Enrico; Pinto, Jorge; Qin, Xiaoxiao; He, Jing; Bevan, David; MacCuish, Norah; MacCuish, John; Chapman, Mitch; Moreland, David – Bioscene: Journal of College Biology Teaching, 2009
One of the difficulties in teaching basic molecular biology concepts to the students with little biological background is the lack of hands-on exercises that combines the challenges of the concepts with visualization and immediate feedback. BIOPS Interactive is a web-based interactive learning environment for molecular biology that complements…

Christensen, Doug – Bioscene: Journal of College Biology Teaching, 2009
An inexpensive and equipment free approach to teaching the technical aspects of DNA sequencing. The activity described requires an instructor with a familiarity of DNA sequencing technology but provides a straight forward method of teaching the technical aspects of sequencing in the absence of expensive sequencing equipment. The final sequence…
