Genome browser at a glance<br />

Genome Browser is a tool for collecting all relevant<br />

genomic sequence data in one site <strong>and</strong> provides<br />

rapid, reliable, <strong>and</strong> simultaneous display <strong>of</strong> any<br />

requested portion <strong>of</strong> genomes at any scale in a<br />

graphical design. The UCSC Genome Browser<br />

resource contains the reference (or <strong>of</strong>ficial) public<br />

DNA sequences <strong>and</strong> working draft assemblies for<br />

human <strong>and</strong> a large collection <strong>of</strong> other genomes.<br />

There are a number <strong>of</strong> tools within this site that<br />

provides access to the sequences themselves, <strong>and</strong><br />

many other useful genome features to add context<br />

to the genomic information. Researchers can use<br />

this site to find genes <strong>and</strong> gene predictions,<br />

expression information, SNPs <strong>and</strong> variations, crossspecies<br />

comparative data, <strong>and</strong> many more.<br />

Moreover, the UCSC provide the ability to search<br />

for markers <strong>and</strong> sequences, to extract annotations<br />

for specific regions or for the whole genome, <strong>and</strong> to<br />

act as a central starting point for genomic research.<br />

It also provides a portal to the ENCODE project.<br />

UCSC genome browser contribution to<br />

research<br />

<strong>Molecular</strong> biologists use UCSC genome browser<br />

modules during their original research tools such<br />

"Genome Browser", "Gene Sorter", 'Blat", "Table<br />

Browser", "VisiGene" <strong>and</strong> "Genome Graphs" all <strong>of</strong><br />

which allow the user to navigate, sort, blast,<br />

visualize <strong>and</strong> analyzes genomic data for reliable<br />

annotation.<br />

Moreover, researchers can learn more about<br />

the object (e.g., known genes, conservation, or<br />

SNPs, etc.) via researching by simply position the<br />

mouse over information line <strong>and</strong> click, then a new<br />

web page will appear with important details <strong>and</strong><br />

information. The Page Index box usually includes<br />

sequences, microarray data, mRNA secondary<br />

structure, protein domain structure, homologues in<br />

other species, gene ontology descriptions, mRNA<br />

descriptions <strong>and</strong> pathways, etc. This wealth <strong>of</strong><br />

information is more than enough for a molecular<br />

biologist as a start point for genomic research.<br />

Colours language in UCSC genome browser<br />

Colors have important meanings in UCSC genome<br />

browser. For instance, the Black color in gene track<br />

indicates a protein data bank (PDB) structure entry<br />

for this genome fragment. Dark blue indicates<br />

NCBI-reviewed sequence, while light blue<br />

corresponds to provisional sequences. In addition,<br />

SNP types are also color-coded. More information<br />

about any specific color representation <strong>and</strong><br />

annotation or descriptive information can be<br />

obtained by clicking the hyperlink <strong>of</strong> the track.<br />

Advantages <strong>and</strong> disadvantages <strong>of</strong> UCSC<br />

genome browser<br />

Advantages<br />

- UCSC Genome Browser is very easy to use <strong>and</strong><br />

free <strong>of</strong> charge online.<br />

- UCSC uses the same interface <strong>and</strong> display for<br />

each <strong>of</strong> the species listed.<br />

- In addition, UCSC can run on (almost) any<br />

computer that has access to internet <strong>and</strong> can<br />

return the results online or by e-mail.<br />

- The Genome Viewer page provides several<br />

options to make changes<br />

- Text search strategy can be used by typing in<br />

gene name, gene symbol, or ID, etc.<br />

- "Automatic Zoom" <strong>and</strong> "Recenter Action" are<br />

h<strong>and</strong>y features to automatically re-center the<br />

image where you click
