When this occurs, click on the item in which you're interested and the Genome Browser will open to that location.</p> <p> The search mechanism is not a site-wide search engine. Instead, it primarily searches GenBank mRNA records whose text annotations can include gene names, gene symbols, journal title words, author names, and RefSeq mRNAs. Searches on other selected identifiers, such as NP and NM accession numbers, OMIM identifiers, and Entrez Gene IDs are supported. However, some types of queries will return an error, e.g. post-assembly GenBank entries, withdrawn gene names, and abandoned synonyms. If your initial query is unsuccessful, try entering a different related term that may produce the same location. For example, if a query on a gene symbol produces no results, try entering an mRNA accession, gene ID number, or descriptive words associated with the gene.</p> -<p><iframe width="560" height="315" src="https://www.youtube.com/embed/5zc9sqd4SD4?rel=0" +<p> +<!--#if expr="${SERVER_NAME} = /-china/" --> + <a href='../../../videos/5zc9sqd4SD4.mp4'> + <img src=../../images/videoIcon.png></a> + + Visit our <a href="/videos/" target="_blank">Video Page</a>. +<!--#else --> +<iframe width="560" height="350" src="https://www.youtube.com/embed/5zc9sqd4SD4?rel=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> </p> +<p> Visit our <a href="https://www.youtube.com/channel/UCQnUJepyNOw0p8s2otX4RYQ/videos" +target="_blank">YouTube channel</a> for more videos. +<!--#endif --> +</p> + <h6>Finding a genome location using BLAT</h6> <p> If you have genomic, mRNA, or protein sequence, but don't know the name or the location to which it maps in the genome, the <a href="../../cgi-bin/hgBlat">BLAT</a> tool will rapidly locate the position by homology alignment, provided that the region has been sequenced.

At a scale of 1 pixel per base pair, the window accurately displays the width of exons and introns, and indicates the direction of transcription (using arrowheads) for multi-exon features. At a grosser scale, certain features - such as thin exons - may disappear. Also, some exons may falsely appear to fall within RepeatMasker features at some scales.</p> <p> Click the <em>zoom in</em> and <em>zoom out</em> buttons at the top of the Genome Browser page to zoom in or out on the center of the annotation tracks window by 1.5, 3 or 10-fold.
