TRANSCRIPT
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

Background LearningDiscussion
Protein Family ProjectExercise I - structure/alignmentDiscussion
Laboratory ProjectExercise II - Sequence analysisDiscussion
• Each student was assigned a protein family
• Start with 3D structure (Cn3D)
• Find homologs (paralogs and orthologs), alignand 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 -

Laboratory Project: Learning by DoingSequencing 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
