Why are you here? Have you taught Genomics before? Plan to teach it soon? Might you teach it sometime? Just curious? Nowhere else to be right now?
Why are we here? Co-taught Genomics Spring ‘06 Louise Temple - Microbiologist sequenced Bordetella avium genome Jon Monroe - Plant Molecular Biologist sequenced several Arabidopsis genes

Protein Family Project - • Each student was assigned a protein family • Start with 3D structure (Cn3D) • Find homologs (paralogs and orthologs), align and build trees • Learning goals - • Link conserved and nonconserved residues from alignment with 3D structure • Use orthologs to see common features • Use paralogs to see unique features

Protein Family Project - Students wrote papers and gave 10-min Powerpoint presentations

Laboratory Project: Learning by Doing Sequencing a viral genome Bacteriophage infecting Bordetella avium Isolated phage DNA Sheared and restriction digested the DNA Cloned fragments into pBluescript Sequenced ~500 clones through VCU Analyzed the sequence - Artemis and Sequencher
Accomplishments: Clones sequenced: ~500, Forward and Reverse ~80% had inserts Number of contigs: ~80, ranging from 2500 to 200 bases Number of genes identified: ~10 highly likely phage genes
