The discovery of the structure of the DNA in 1953 had
a major impact on every field of biological research. Cloning techniques
allowed the characterization of developmental mutants at the molecular
level. Many signal transduction pathways and DNA-binding motifs were discovered
in Drosophila, which later turned out to be astonishingly conserved
between flies and other species. A first example, the homeobox, was first
discovered in flies, in the labs of Walter J. Gehring and Matthew P. Scott.
