Hello, The dark bar is an exon - this display is an indication that there is a base level alignment at this position between the EST and the genome. The rest of the data (other sequences) appears to support the idea that this is instead an intronic region (no mRna/Est alignments at this location, but at locations at one or either edge).
Zoom out a few levels to see the big picture. Then try 10x to see where the other sequence have exons. We hope this helps, Jennifer ------------------------------------------------ Jennifer Jackson UCSC Genome Bioinformatics Group ----- "Chuangye" <[email protected]> wrote: > From: "Chuangye" <[email protected]> > To: [email protected] > Sent: Monday, November 9, 2009 4:14:28 AM GMT -08:00 US/Canada Pacific > Subject: [Genome] What differences between these ests > > Dear sir, > > Thank you for reading my Email! > > First, please set "chr3:173,402,247-173,402,431" in your > "position/search" > of UCSC Browser.
