4. Justification (assessment or accreditation based) for new course or course revision or course renumbering:

In the last decade genome sequencing and comparative genomics have begun revolutionize the biological sciences, producing a large and ever-growing body of new data on how biological information is stored and expressed. This, in turn, has had profound impacts on how biologists understand the organization and evolution of genetic blueprints controlling cell function and development. Because of its rapid development of comparative genomics, and the enormous amount of new information that has emerged, standing Biology graduate course curricula cannot incorporate in-depth coverage of the field. Nevertheless, understanding the fundamentals of genomics is becoming increasingly important for graduate students in the Biology program, and for biomedical and health-related graduate students in the IDPBS and other graduate programs. Although the current Biology curriculum includes courses in which graduate students gain experience in the basic methodologies employed in comparative genetics and genomics, as yet we offer no courses that synthesize new research results into a cohesive learning experience. Comparative genomics impact a wide array of biological and biomedical research fields, from human gene therapy to plant population ecology. In addition to its importance for the Biology Graduate Program, this course will meet a growing need for coursework in the

Interdisciplinary Doctoral Program in the Biological Sciences (IDPBS) that provide a common language and body of biological knowledge important to the various interdisciplinary fields covered by participating faculty mentors. As such, this course can contribute to curricula of other graduate programs, with the potential to be incorporated into the core coursework for the IDPBS.

A) Textbook

The Evolution of the Genome , T. Ryan Gregory, (Ed.) 2005. Elsevier Inc, Oxford, UK. ISBN: 0-12-310463-8.

B) Course objectives

Students taking this course will:

 demonstrate knowledge of basic genome characteristics and how they evolve through time.

 explain major developments in comparative genomics and interpret how they relate to other biological subjects.

 employ library research collections and on-line resources to uncover and examine the most recent literature in comparative genome evolution.

 organize and synthesize ongoing research developments in comparative genomics and translate this research to their student peers.

 gain proficiency in interpreting and presenting results of modern genomic research, and in explaining in both written and oral formats.

C) Course content outline

The following subjects form the core of the initial curriculum. Topics will be updated through time based on new and important results in comparative genomics. The major subjects will be presented in two hours of lecture per week.

The third hour is reserved for seminar/discussion sessions, led by students, on recent primary literature and review papers.

1) Genome Structure a) How are genomes organized? i) Prokaryotic genomes ii) Eukaryotic genomes iii) How structure impacts evolutionary change

2) Genome Size Variation a) Range of sizes and consequences i) How genomes vary in size among organisms. ii) Mechanisms for changes in genome size. iii) Genome size and developmental complexity. iv) C-value paradox

3) How individual sequences change through time a) Sources of variation i) Mutations; causes and rates.
