(12) According to these and previous data, the AS-C is organized, distally to proximally, as follows: the achaete region, with most of its DNA (10 kb) located upstream from the putative achaete (T5) gene; an intermediate region, approximately 18 kb long, whose deletion only weakly affects the scute function; and the scute region, with most of the DNA critical for its function extending 4-5 kb upstream and 50 kb downstream of the putative scute (T4) gene.
