Insertion of the reporter cassette into the E. coli K-12 MG1655 genome. The chromosome positions of oriC and dif labelled, relative to the coordinate system origin (32). The structured macrodomains, Ori, Right, Ter and Left, are represented as coloured arcs with macrodomain boundaries shown inside the circular map (4). The non-structured left and right regions are labelled as NSL and NSR respectively. The orientation of the reporter cassette at the chromosome insertion sites is indicated by a black arrow.
