Cytology
Description

14.5kb DNA containing the region -13.5 and -28kb relative to the Ubx transcription start site regulates expression of lacZ.

(Chinwalla et al., 1995)

A 14.5kb fragment of bxd regulatory region of Ubx (coordinates -18.5kb to -4kb on the BX-C walk) is fused upstream of Ecol\lacZUbx.P140.
