Why Genomics?
http://cs173.stanford.edu [BejeranoWinter12/13] 5
• This century is owned by Genomics.
• Growing impact on everybody’s life.
• Rewriting the book on our understanding of life.
• Genomics is an information/computational science.
• “There is gold in them thar hills”
• That gold can be yours.
![Page 6: MW 11:00-12:15 in Beckman B302 Prof: Gill Bejerano TAs: Jim Notwell & Harendra Guturu](https://reader036.vdocuments.us/reader036/viewer/2022062410/56816581550346895dd81e2e/html5/thumbnails/6.jpg)
Why Genomics?
http://cs173.stanford.edu [BejeranoWinter12/13] 6
• “There is gold in them thar hills”
• That gold can be yours.
• Make tantalizing discoveries with CS107 proficiency.• Knowing more CS does make you more dangerous.
![Page 7: MW 11:00-12:15 in Beckman B302 Prof: Gill Bejerano TAs: Jim Notwell & Harendra Guturu](https://reader036.vdocuments.us/reader036/viewer/2022062410/56816581550346895dd81e2e/html5/thumbnails/7.jpg)
Genomics is different
http://cs173.stanford.edu [BejeranoWinter12/13] 7
Theoretical CS studies the hardness of questions.A question is as hard as its easiest solution.A lot of focus on how to answer.
• Order of importance in genomics:• What to ask?• Why ask it?• How to answer?• What does my answer mean?
Genomics is drowning in data.Much to discover. Some fascinating, lots quite boring.Focus on what & why to ask, and can we answer?
![Page 8: MW 11:00-12:15 in Beckman B302 Prof: Gill Bejerano TAs: Jim Notwell & Harendra Guturu](https://reader036.vdocuments.us/reader036/viewer/2022062410/56816581550346895dd81e2e/html5/thumbnails/8.jpg)
Why Genomics?
http://cs173.stanford.edu [BejeranoWinter12/13] 8
• “There is gold in them thar hills”
• That gold can be yours.
• Make tantalizing discoveries with CS107 proficiency.• Knowing more CS does make you more dangerous.
• Reject the “us” (CS) and “them” (BIO) dichotomy.• Read what you need.• Develop your own taste for questions and answers.

MaterialsHow many people need the BIO primer?We’ll have three primers on:Biology; Text Processing; and the UCSC Genome Browser.Programming background recommended (CS107 level)
Homework (schedule on website):Two individual homework assignments,
plus a group project.Instead of an exam we’ll have a project 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

Topics(0) Genome context:
cells, DNA, central dogma(1) Genome content / genome function:
coding and non-coding genes, gene regulation, repeats, epigenetics, signaling
(2) Genome sequencing: technologies, assembly/analysis, technology dependence
(3) Genome evolution: evolution = mutation + selection, modes of evolution, comparative genomics, ultraconservation, exaptation
(4) Genomics & disease:disease susceptibility, cancer genomics, treatment response, personal genomics, gene therapy

Important in Genomics
http://cs173.stanford.edu [BejeranoWinter12/13] 13
• Understand deep dependence on technology.• The only truth in genomics is…• Technology dictates what can be asked.• Technology dictates how it can be answered.• Recent data deluge – the beauty, and the risks.
• Hypothesize, code, analyze, repeat until you find gold, or your sieve is empty.
• Analyze ensembles, learn from outliers.
• When you make an exciting discovery, first try hard to refute it.• If it’s too good to be true, it is most likely not true.• Seek the exciting invisible but plausible.

Further Reading
http://cs173.stanford.edu [BejeranoWinter12/13] 14
These principles and tips will be revisited at course’s end.At which point we will ask ourselves:
Are we any wiser?
Check out the Bejerano lab “resources” page:• Popular science books• Core Stanford classes• Core technical books/skills
What if I get hooked?Classes, rotations, CURIS, honors theses, etc.

• Human genome encodes 20-25,000 genes (2% genome),>1,000,000 genomic switches that control genes (>10%).
• Gene = genomic substring that encodes HOW to make a protein.
• Genomic switch = genomic substring that encodes WHEN, WHERE & HOW MUCH of a protein to make.

1st Genome Assembly
1. Find overlapping reads
4. Derive consensus sequence ..ACGATTACAATAGGTT..
2. Merge some “good” pairs of reads into longer contigs
3. Link contigs to form supercontigs
Some Terminology
read a 500-900 long word that comes out of sequencer
mate pair a pair of reads from two endsof the same insert fragment
contig a contiguous sequence formed by several overlapping readswith no gaps
supercontig an ordered and oriented set(scaffold) of contigs, usually by mate
pairs
consensus sequence derived from thesequene multiple alignment of reads
in a contig
