Graphical Abstract

Caption

In the developing fly embryo, four "gap genes" make protein molecules that encode information about the position of stripes that form on the embryo. The researchers found that combinations of the four proteins specify unique locations along the embryo's length where "pair-rule" gene activity leads to creation of the stripes.
