(left) Chromosome 9. A schematic map of a chromosome shared by all the great ape, showing our degree of relatedness.?(right) A map of a human proteome. The molecules from a drop of human blood are mapped by weight (left to right), and by slipperiness (top to bottom). The reason that multiple stripes appear in series is that the atoms in proteins come in different isotopes creating variations that different in weight by a single neutron.
