Hi Jane,
Thank you for your question about visualizing and obtaining sequence for
cDNAs in the UCSC Genome Browser.
Some tracks in the UCSC Genome Browser contain cDNA sequences, such as
the "mRNAs" tracks. For example, here is the description page for the
"Human mRNAs" track on the hg38/GRCh38 assembly of the human genome:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg38&g=mrna. Here you can
see this mRNAs track in the Genome Browser alongside the GENCODE v22
track for the SOD1 gene:
http://genome.ucsc.edu/cgi-bin/hgTracks?hgS_doOtherUser=submit&hgS_otherUserName=mspeir&hgS_otherUserSessionName=hg38_Sod1mRnaMlq
We just released a YouTube video that details how to obtain the sequence
for items in the track of your choice:
http://genome.ucsc.edu/training/vids/index.html#vid08. I would start at
time "5:40" in the video, which is where the steps describing how to get
sequence begin. While the video describes getting the sequence for items
in a different track, you can adapt the steps to your needs by selecting
"group: mRNA and EST", "track: Human mRNAs", and "table: all_mrna".
I hope this is helpful. If you have any further questions, please reply
