Summary

Summary

Integrated Genomics: A Discovery-Based Laboratory Course introduces the excitement of discovery to the basic molecular biology laboratory. Utilizing up-to-date molecular biology protocols and a basic experimental design, this text offers experience with three different model systems. Students will become familiar with the simplicity and power of single-celled organisms, Escherichia coli and Saccharomyces cerevisiae, as they search for genes that interact and function within the nematode Caenorhabditis elegans .

Incorporated throughout the course are exercises designed to offer students familiarity with the wealth of bioinformatics data that can be accessed on the World Wide Web. Following completion of interaction studies within the yeast, the course is designed to allow students to examine the functional consequences of reducing a gene's function within the multicellular worm that is both simple and inexpensive to maintain within a laboratory. The inclusion of alternative experiments allow for flexibility in determining the ending date or goal of the laboratory, as well as working within the available budget and resources of most any classroom environment.

Further striking features of this title are:

An accompanying Web site providing PowerPoint slides, plus links to the internet, and regular updates as bioinformatics databases evolve and methods improve. www.wiley.com/go/caldwell Inclusion of modern genomic/proteomic technologies such as the yeast two-hybrid system and RNAi Detailed experimental protocols and easy access to instructional materials

This discovery-based laboratory course provides excellent practical training for those pursuing career paths in biomedicine, pharmacy, and biotechnology.

Shelli N. Williams, PhD , is a research scientists at a private forensic company based in Virginia. Following her early graduation Magna cum laude from undergraduate studies, Dr Williams began her graduate work in the laboratory of Drs Guy and Kim Caldwell at The University of Alabama, where she earned her doctorate from The University of Alabama in 2006. Dr Williams served as an adjunct faculty member in New College, an interdisciplinary department at The University of Alabama, where she was the instructor of a seminar course demonstrating how the nature of the laboratory experience plays an essential role in the understanding and advancement of science. She has experience plays an an essential role in the understanding and advancement of science. She has experience teaching introductory biology courses to both majors and non-majors students and has been a repeated guest lecturer in a cross-disciplinary bioethics class. As a PhD candidate, Dr Williams served as a teaching assistant for Integrated genomics, a discovery-based genomics course funded by the Howard Hughes Medical Institute. Dr Williams was named the recipient of two university-wide Graduate Council Fellowships, as well as receiving recognition as an Isabella Hummel graham Scholar honoring outstanding female students throughout the university. She also received a competitive Worthington Biochemical Travel Award from the American Society of Cell Biology, Placing her among the highest honored student researchers at their 2003 Conference. Subsequent graduate work establishing Caenorhabditis elegans as a model for epilepsy was high-lighted in news releases by the Howard Hughes Medical Institute. In recognition of her accomplishments, Dr Williams was awarded the 2005 Joab Langston Thomas Award, the top honor for PhD students in Biological Sciences at the University of Alabama.

Kim A. Caldwell, PhD , is an Assistant Professor in the Department of Biological Sciences at The University of Alabama. Dr Caldwell is a Faculty Affiliate of The University of Alabama Center for Green Manufacturing and she is an Adjunct research Assistant Professor in the Department of Neurology at the University of Alabama at Birmingham Medical School. Dr Caldwell, a native of the Buffalo area, received her undergraduate degree in recombinant Gene Technology from the State University of New York at Fredonia and her MS and PhD degrees in Biotechnology and Cell, Molecular & Developmental Biology, respectively, from The University of Tennessee, While at Tennessee, Dr Caldwell was a four-time recipient of the Oak Ridge National Lab-UT Science Alliance teaching/research Award and the Chancellor''s Award for Extraordinary Professional Promise. Following receipt of her doctorate, she held postdoctoral research appointments at the Rockefeller University and Columbia University in New York, during which time he was named the recipient of a Revson Fellowship and a National research Service Award from the National Institue of Child Health and Human Development. Her research has been published in many outstanding peer-reviewed journals, including Nature, Proceedings of the National Academy of Sciences, Journal of Neuroscience, Human Molecular Genetics the Journal of Cell Science and Development. Dr Caldwell serves as Director of the Howard Hughes Medical Institute rural Science Scholars program at Alabama. Additionally, she has designed and taught courses in General Biology, a seminar on the societal impact of the Human Genome Project, and a course entitled '' the Language of research'', which she teaches jointly for Howard Hughes research Interns at both Stillman College and the University of Alabama. For her teaching efforts,in 2005 Dr Caldwell was selected as a Education Fellow in the Life Sciences of the National Academy of Sciences.
