Forward genetics involves the identification of an unknown DNA sequence (genotype) associated with the expression of that sequence (phenotype). This is often done by generating variants (mutants) of that feature. One of the most practical methods is transposon mutagenesis, which facilitates the genotype-phenotype association through a sequence…

DNA barcoding is an important molecular methodology for species identification that was developed over the last two decades and it should be covered in the biology bachelor curriculum. Here, we present an example of DNA barcoding by sequencing a segment of the 28S nuclear ribosomal large subunit rRNA gene of wild mushrooms and framing the…

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure-function relationships, such models have not been widely implemented in biochemistry classrooms.…

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…

Genomics and proteomics projects have produced a huge amount of raw biological data including DNA and protein sequences. Although these data have been stored in data banks, their evaluation is strictly dependent on bioinformatics tools. These tools have been developed by multidisciplinary experts for fast and robust analysis of biological data.…

Emerging interest in genomics in the scientific community prompted biologists at James Madison University to create two courses at different levels to modernize the biology curriculum. The courses are hybrids of classroom and laboratory experiences. An upper level class uses raw sequence of a genome (plasmid or virus) as the subject on which to…

Discusses interdemic (interpopulation) selection, the Levins and Boorman-Levitt models, and the significance of group selection for ecology. (JR)

Discusses the mechanisms of genetic recombination with particular emphasis on the study of the fungus Sordaria brevicollis. The study of recombination is facilitated by the use of mutants of this fungus in which the color of the ascospores is affected. (JR)

There is a scarcity of research evaluating the effect of the classroom exposure of students to historical and/or female role models in the sciences. This paper describes a unit involving an historical female role model that was incorporated into a college-level science course. The goals of the unit were to provide an historical context for…

Discusses recent advances in culturing somatic cells of plants that now make it possible to apply the powerful techniques of microbial genetics to higher life forms. (Author/JR)

Discusses immunological methods used to demonstrate or verify relationships between species of animals. (HM)

Examines the relationships between self-concept and achievement in students studying genetics. Also examined were differences in self-concept and achievement between men and women and between science majors and nonscience majors. (CS)

Presents insights into the endosymbiotic theory based on a re-examination of evidence from investigations into the archaebacteria and other strange organisms inhabiting the hindguts of wood-eating insects. Examines the mechanism of evolutionary change and the speed with which it occurs. (RT)

Presents a review of genetic engineering, in which the genotypes of plants and animals (including human genotypes) may be manipulated for the benefit of the human species. Discusses associated problems and solutions and provides an extensive bibliography of literature relating to genetic engineering. (JR)

Describes redesigning of a genetics course on the basis of Pella's referents, Banathy's system, and Bloom's taxonomy in effort to evaluate affectively behavioral changes among reference groups of science and nonscience majors, in addition to genetics students. Indicates preference of learning environment to course content in results analysis. (CC)
