Transgenic construct used in an enhancer-blocking assay to study the function of the dwg protein and its interactions with the scs chromatin domain boundary element. A fragment containing two copies of the BSwt oligonucleotide from region C of the scs insulator element has been inserted into P{wRW}, between the w enhancer and the w transcription unit, in forward orientation.
Construct: 0.5kb of scs' sequences.
Construct: Included in a fragment containing two copies of the BSwt oligonucleotide from region C of the scs insulator element.
