Goals [Bejerano Fall11/12] 2

3 Goals Meet your genome (learn to surf, learn the surf) Understand genomic tools (theory, applications) DIY (pose questions, use tools, write code, get answers)

[Bejerano Fall11/12] 4 Materials How is the class split between CS and BIO? We’ll have three Friday sessions starting this Friday 10am, in B-302: Bio Primer; Text Processing Primer; UCSC Genome Browser Primer. Strong programming background recommended (CS107 level) Homework (schedule on website): Two individual homework assignments (theory + practice), plus a group project. Instead of an exam we’ll have a milestone and a final poster session. Attendance is mandatory (for grade). You may skip 2 lectures without affecting your grade. Get on the mailing list! Reading Material: mostly journal papers

[Bejerano Fall11/12] 5 Topics Topics will include: (1) genome sequencing: technologies, assembly, personalized sequencing (2) functional landscape: genes, regulatory modules, repeats, RNA genes, epigenetics (3) genomic contribution to human disease and disease susceptibility (4) genome evolution: evolutionary processes, comparative genomics, ultraconservation, exaptation As time permits, we may cover population genetics and personalized genomics, ancient DNA, metagenomics, or other current topics. Discuss difference from CS262 (Winter), CS374(Fall), Gene203(Fall)

Asides Biology is very complex. Beautiful truths can be gleaned with little knowledge. We’ll start with a bird’s eye view and gradually dive in. But we still won’t exhaust the depth of any single topic. Feedback always welcome. [Bejerano Fall11/12] 6
