Human genome map, computer artwork. This image was created by rendering all the DNA strands that make up the human genome into a planet-like sphere (centre). The sphere is superimposed onto a two-dimensional genome map and line drawings. Gene density is coloured green for high density and blue for low density. Yellow lines represent the regulation of other genes by the genes that control inflammation and tumour formation. This map is one of a series of genomic planets created by German biologist Thomas Fester.
