Doc element inserted into w promoter region.
Insertion of 4.9kb Doc element, close to the site of transcription initiation. 13bp of w sequence from +3700 to +3688 is duplicated, and is present at both ends of the Doc insertion (nucleotide positions as in FBrf0041384). The Doc element is inserted in the same orientation as the direction of w transcription.
5kb Doc insert at +3.71; Origin = insertion of wa copia; '-' values to left (telomere) end; '+' values to right (centromere) end.
