 <h2>Genome Browser Orientation and Navigation</h2>
 <p>
 The standardized reference genome displayed on the 
 <a href="../../cgi-bin/hgTracks?db=wuhCor1">COVID Genome Browser</a> is from one of the first isolated
 cases, known as <a href="https://www.ncbi.nlm.nih.gov/nuccore/NC_045512.2" 
 target="_blank">NC_045512v2</a> or wuhCor1. With more than 80 track datasets across the 
 SARS-CoV-2 reference genome's nearly 30,000 RNA
 bases, navigation is essential to finding the information you want to see. Below is an example
 view of the SARS-CoV-2 Genome Browser with labeled sections highlighting the navigation, 
 reference sequence, annotations, and other available track datasets.</p>
