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
