the human genome
In some regions, genes are crowded together much like buildings in urban centers. In other areas, genes are spread over the vast expanses like farmhouses on the prairie. And then there are large tracts of desert, where only non-coding ‘junk DNA’ can be found. Each region tells a unique story about the history of our species… This landscape contrasts starkly with the genomes of many other organisms, such as the mustard weed, the worm, and the fly. Their genomes more closely resemble uniform, sprawling suburbs, with genes relatively evenly spaced along chromosomes.
