11.1 Introduction 11.2 Lytic development is divided into two periods 11.3 Lytic development is controlled by a cascade 11.4 Functional clustering in phages T7 and T4 11.5 Lambda immediate early and delayed genes are needed for both lysogeny and the lytic cycle

10.1 Introduction 10.2 Regulation can be negative or positive 10.3 Structural gene clusters are coordinately controlled 10.4 The lac genes are controlled by a repressor 10.5 The lac operon can be induced 10.6 Repressor is controlled by a small molecule inducer
