S.cerevisiae genome is available for viewing using a Java map display tool,
DerBrowser. Among other features, it allows for quering external data
sources: SacchDB, MIPS, YPD and GeneQuiz. Point your Java-aware browser
to this test URL:
http://www.mpimg-berlin-dahlem.mpg.de/~andy/DerBrowser/genomes/S.cerevisiae/
The connection to Germany may be slow so please be patient when the applet
loads.
Enjoy and don't hesitate to comment,
