Nearly every cell in the human body carries a copy of the full human genome. So how is it that the cells that detect light in the human eye are so different from those of, say, the beating heart or the spleen?

When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of that DNA doing?
