[Localization of transcripts corresponding to different regions of the "cut" locus in Drosophila embryos].

Transcripts of the cut locus were localized in Drosophila embryos with use of nonradioactive in situ hybridization. DIG-labeled probes were generated from two locus regions located at position -130. Distal and proximal regions were found to be transcribed in the same tissues throughout embryogenesis. As only the proximal region transcript was detected, the conclusion was made that two or more various transcripts derived from different regions of the locus and under common control, are present simultaneously in the embryonic cells.
