In eаch diаgrаm, the lac оperоn is represented by a rectangle that is divided intо 6 segments that are labeled from left to right as follows: C A P Site, an unlabeled segment, Operator, lac Z, lac Y and lac A. In each diagram, an oval labeled R N A Polymerase is positioned under the right half of the C A P site, the unlabeled segment, and the left one fourth of the Operator. In the top diagram a rectangle with a triangular notch at the bottom is labeled Repressor, and it sits under and touches the right one third of the Operator, lac Z, and the first one third of lac Y. An X is marked on the right side of the R N A polymerase, and an arrow extends from the X to the repressor. In the bottom diagram a rectangle with a semicircular notch at the bottom is labeled Repressor, and it does not contact the lac operon. Instead a circle labeled allolactose fits into the semicircular notch of the repressor. An arrow extending from the R N A polymerase points to the right. Figure 1.
