29.1 Introduction 29.2 Fly development uses a cascade of transcription factors 29.3 A gradient must be converted into discrete compartments 29.4 Maternal gene products establish gradients in early embryogenesis 29.5 Anterior development uses localized gene regulators

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

19.1 Introduction 19.2 The nucleosome is the subunit of all chromatin 19.3 DNA is coiled in arrays of nucleosomes 19.4 Nucleosomes have a common structure 19.5 DNA structure varies on the nucleosomal surface

15.1 Introduction 15.2 Insertion sequences are simple transposition modules 15.3 Composite transposons have IS modules 15.4 Transposition occurs by both replicative and nonreplicative mechanisms
