This feature shows the actual DNA sequence at very detailed zoom levels (< 170 bp). At lower resolution it shows a graph of the G+C content. At zoom levels above 50,000 bp this feature is hidden due to performance restrictions. The sequence was copied from NCBIs hg19 alignment and can be downloaded from NCBI for your reference. Note that you can also download the current sequence of your display in various formats by using the sequence dumper (Reports & Analysis: Download Sequence File).
