A new picture of gene and chromosome structure is emerging in Drosophila that differs considerably from that largely derived from polytene chromosome banding patterns and saturation mutagenesis. In particular, gene transfer has enabled us to more clearly limit the functional unit of a number of genes. Gene regulation may be studied at the molecular level with such techniques. The possible complexity of regulatory elements that may pose problems in their analysis is discussed.
