2. Options I. Genome Browser II. ENCODE III. Blat IV. Table Browser V. Gene Sorter VI. In Silico PCR VII. Proteome Browser VIII. Utilities IX. Downloads

3. I. Genome Browser Human (Homo sapiens) Genome Browser Gateway Provides any section of entire human genome Non-Standard Join Certificates – some sequence joins between adjacent clones in this assembly could not be computationally validated the sequencing center responsible for the particular chromosome provides an electronic certificate –should state why the submitter thinks the join is valid

4. Query Clade: 具有相同祖先的一群生物 vertebrate: 脊椎動物 deuterostome: 後口類 insect: 昆蟲 nematode: 線蟲

5. Chimp: 黑猩猩 Rhesus: 恆河猴 Opossum: 負鼠 X. tropicalis: 蛙 Tetraodon: 河豚 Fugu: 河豚

7. Entire chromosome – chr7 (all of chromosome 7) Cytological band – 20p13 (region for band p13 on chr 20) Chromosomal coordinate range – chr3:1-1000000 (first million bases of chr 3, counting from p arm telomere) mRNA, EST, or STS marker Keywords from the GenBank description of an mRNA (huntington)

14. Gen Browser Syntax (x) Entire chromosome – chr7 (all of chromosome 7) Cytological band – 20p13 (region for band p13 on chr 20) Chromosomal coordinate range – chr3:1-1000000 (first million bases of chr 3, counting from p arm telomere) mRNA, EST, or STS marker Keywords from the GenBank description of an mRNA (huntington)

15. II. ENCODE Stands for “Encyclopedia Of DNA Elements” Public research consortium to carry out a project to identify all functional elements in the human genome sequence Launched by The National Human Genome Research Institute (NHGRI) Conducted in three phases: – pilot project phase (survey existing methods) – technology development phase (develop new methods) – planned production phase (…)

16. ENCODE Formats Browser Extensible Data Format (BED) – for efficient access to genomic annotations General Feature Format (GFF) – for data where there are a set of linked features Gene Transfer Format (GTF) – a refinement of GFF that tightens the specification Multiple Alignment Format (MAF) – a series of multiple alignments in one format Wiggle Format (WIG) – for continuous-valued data in track format

17. ENCODE Options Regions (hg16) – old database (+mRNA, EST, & STS markers) Regions (hg17) – new database (+mRNA, EST, & STS markers) Data Status – the current status of ENCODE datasets Downloads – sequence and annotation data downloads Submission – for the submission of ENCODE-related data
