Grading Scale: Students will be assigned grades using a traditional grading scale (A, B, C, D, and F).

WRITING ASSIGNMENT

Each student is required to write an overview of his/her dissertation or thesis research project.  The overview is limited to a 1 to 2 page Project Description and a References Cited page(s) (i.e., a page providing an alphabetized listing of publications cited in the Project Description).  The Project Description should provide key background information, outline the main goals of the project, and provide an overview of the methods to be utilized.  In addition, it should clearly discuss the value of the project (directly or indirectly) to humankind.  Students can summarize preliminary research results if desired.  The Project Description should be prepared so that it can be readily understood by someone with a moderate knowledge of biology (e.g., someone with a B.S. degree in biological sciences).  References should be cited in the text and listed on the References Cited page using the format described below.  Ask Dr. Peterson if you have questions about citation format and appropriateness.

Citing References

References should be cited in the text using the Harvard (name−date) system. Where there are three or more authors, only the first author's name should appear, followed by et al. Where several references are cited at the same point in the text, these should be arranged in chronological order. In the References Cited list, citations should be arranged in alphabetical order. References should include: names and initials of all authors; year of publication; full title of the article; source using abbreviations for journals as shown in Index Medicus; volume number; and first and last page numbers. Abstracts should be identified as such. For citations from books, the chapter title should be followed by the names and initials of all editors, the title of the book, edition, place of publication, publisher and first and last page numbers.

Examples:

Bunge J, Epstein SS, Peterson DG (2006) Comment on "Computational Improvements Reveal Great Bacterial Diversity and High Metal Toxicity in Soil." Science 313: 918.

Lamoureux D, Peterson DG, Li W, Fellers JP, Gill BS (2005) The efficacy of Cot-based gene enrichment in wheat (Triticum aestivum L.).  Genome 48: 1120-1126.

Peterson DG (2005) Reduced representation strategies and their application to plant genomes.  In: The Handbook of Plant Genome Mapping: Genetic and Physical Mapping. Edited by: Meksem K, Kahl G. WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, Germany. pp. 307-335.

Wicker T, Robertson JS, Schulze SR, Feltus FA, Magrini V, Morrison JA, Mardis ER, Wilson RK, Peterson DG, Paterson AH, Ivarie R (2005) The repetitive landscape of the chicken genome.  Genome Res. 15: 126-136.

Only accepted papers should be referenced; all other material should be referred to in the text as 'in preparation', 'personal communication,' or 'unpublished observations' and should not be included in the reference list.

World Wide Web: All references should include the same information that would be provided for a printed source (or as much of that information as possible). The Web information is then placed at the end of the reference. It is important to use "Retrieved from" and the date because documents on the Web may change in content, move, or be removed from a site altogether. To cite a Web site in text (but not a specific document), it is sufficient to give the address (e.g., http://www.apa.org) there and no reference entry is needed. However, when citing a particular web page a citation in the text (e.g., Gaten 2000) and an entry in the reference list will be required.

For example:

Gaten E. (2000) Internet references. Retrieved from http://www.le.ac.uk/biology/teach/mod300/ecitations.html on 19-Sep-2000.

One of the most comprehensive guides to citing internet references is provided by the American Psychological Association: http://www.apastyle.org/elecref.html

4. JUSTIFICATION AND LEARNING OUTCOME
Justification
The DNA of an organism is referred to as its genome.  An organisms genome contains it genes, i.e., those DNA sequences that underlie the heritable traits that are responsible for the appearance, structure, function, and ultimately the evolutionary success/failure of that organism.  While genes are not the only sequences found in genomes, genes function and evolve within the context of genomes.  Consequently, genome research represents a gateway through which we may be able to understand and manipulate genes in living organisms.  The potential applications of such knowledge include curing human/animal/plant diseases, manufacturing patient-specific pharmaceuticals, improving crop plants and domesticated animals, development of cost effective biofuels, and more efficient protection of the planets biological diversity.

Genomics is a rapidly growing branch of genome research in which robotics, automated DNA sequencing, and advanced computational methods are used to rapidly and efficiently characterize the genes and numerous other DNA sequences found within genomes.  Ultimately the goal of genomics is to understand genes and their relationships to each other, non-gene sequences, proteins, metabolic pathways, and morphological and physiological characteristics.  Such an ambitious goal requires the participation of numerous scientists with diverse backgrounds including molecular biologists, computer scientists, engineers, plant/animal breeders, mathematicians, statisticians, physicists, chemists, etc.  The multi-disciplinary nature of genomics and its potentially enormous benefits have made genomics a rapidly growing industry, employing a diverse group of hundreds-of-thousands of individuals worldwide.

It is to the advantage of Mississippi State University to provide its students with the background they need to participate in a workplace in which genomics is becoming more and more prevalent.  However, at present there is no regular course taught at MS State that has genome biology/genomics as its central focus.  Genomes and Genomics will remedy this deficiency in a way that engages students from multiple disciplines across campus and help prepare them for active roles in genomic research.
