Gene Organization in prokaryotes and a range of eukaryotes


    Note that prokaryotic bacteria lack introns. The human genome is about ten-fold larger than that of Drosophila. However, humans do not have a substantially larger number of coding genes than Drosophila: humans genes are more spread out in the chromosomes, and typically have a higher proportion of introns.
