Genome map of yeast (Saccharomyces cerevisiae), computer artwork. This map was created by rendering all the DNA strands that make up the yeast's genome into a planet-like sphere. Gene density is coloured green for high density and blue for low density. Orange, at the top, is mitochondrial DNA. Clouds were added for aesthetic reasons. This map is one of a series of genomic planets created by German biologist Thomas Fester.
