Bithorax mutant

WebThe iab-2, 3, and 4 mutant classes define positive cis-regulatory elements that induce expression of abdA in segments A2-A4 (parasegments 7-9), respectively. Once a pattern of abdA expression is turned on in a given parasegment, it remains on in the more posterior parasegments, so that the complex pattern of expression is built up in the ...
