How to zoom-in on selected coordinates in UCSC genome browser

To zoom in on a selected region, we can high-light a region and then select zoom-in.

Alternatively, we can type the chromosome number and coordinates into the search window:

In this example, we see introns

The dashed line of MSH2 locus indicate introns.



The blocks in this picture are exons with coding regions,

In the following picture, the circled regions are 5' untranslated regions, i.e., 5'UTR, because this region is at the 5' end of "ATG". Notice that 5'UTR is also in an exon.
