Figure 1. Visualizing live transcription from the seven stripes of D. melanogaster even-skipped.

Figure 1.

(A) Simple model of transcriptional bursting by promoter switching between ON and OFF states. (B) The promoter switching parameters define the burst duration, the duration between bursts, and amplitude. (C) Wild-type eve locus showing the five stripe enhancers (1, 2, 3+7, 4+6, 5) and the late enhancer element. Colors for individual stripes are used throughout figures. (D) Layout of the engineered eve BAC showing the locations of the MS2 stem loop array and yellow gene.
