Genome maps. Computer artwork of genome maps rendered as planet-like spheres. From upper left going anti-clockwise, the spheres represent the genomes of Mycoplasma genitalium, the extremophile Methanococcus janaschii, the yeast Saccharomyces cerevisiae, the plant Arabidopsis thaliana, the fruit fly Drosophila melanoganster and human. The background pattern shows part of the salamander (Necturis lewisi) genome. This map was created by German biologist Thomas Fester for his 'genomic planets' gallery.
