Associated with the transcripts are colored arrows that indicate the types of evidence that were used to annotate the gene. A green stripe means that there is sequence similarity to another sequence in GenBank. The gene name appears adjacent to the evidence arrow. The gene name appears on the display only when you zoom in enough for the name to fit. Transcripts are identified by CT ID numbers.
Many genes have a single transcript, but some have several different transcripts.
Their names appear as you zoom in. Sequence gaps are represented by red zig-zags along the central axis. If the length of the sequence gap is known, it is represented by length of the red zig-zag. If the length is not known, the length of the red zig-zag defaults to 1000 bases. Sequencing by the BDGP over the next few months will eliminate most or all of the sequence gaps.
