Hello Josephine, Please see the details page for the UCSC genes track (scroll down to "Methods"): http://genome.ucsc.edu/cgi-bin/hgTrackUi?c=chr21&g=knownGene
The details page for the knownAlt track is here: http://genome.ucsc.edu/cgi-bin/hgTrackUi?c=chr21&g=knownAlt In case it isn't clear, the knownAlt track is created with UCSC Genes. This previously answered mailing list question touches on the topic you are asking about, though goes into more detail than you might want: https://lists.soe.ucsc.edu/pipermail/genome-mirror/2006-November/000207.html I hope this information is helpful to you. Please don't hesitate to contact us again if you require further assistance.
