Amy never knew whom Mr. Devon worked for--the organization that's after her, or some other secret government agency. All she knew was that he seemed to be her ally. He always appeared just when she needed help or vital information. But ever since Mr. Devon's death, Amy has relied on her own smarts to survive. And she'll need them more than ever now that a new substitute teacher at school has it in for her. Ms. Heartshorn has a reputation for being demanding. She doesn't tolerate fools or careless work. And her feedback can be . . . well, a little harsh. Amy hates her. But when she learns why Ms. Heartshorn is really at school, Amy totally flips out.

Amy thinks being perfect can be a real drag. Everyone expects her to behave responsibly and to use her extraordinary talents for good. But when she meets one of her clones--an unexpected Amy, Number Thirteen, who goes by the name Aly--she gets a taste of normal teen life and wants more. Aly is a reject from Project Crescent. She runs with a wild crowd whose motto is Good Times Now! She convinces Amy to hang loose and have fun. Drawn by Aly's free spirit, Amy rejects her genetic roots. But Aly's carefree ways come at a high cost. . . .

The Initiation of DNA Replication contains the proceedings of the 1981 ICN-UCLA Symposia on Structure and DNA-Protein Interactions of Replication Origins, held in Salt Lake City, Utah on March 8-13, 1981. The papers explore the initiation of DNA replication and address relevant topics such as whether there are specific protein recognition sites within an origin; how many proteins interact at an origin and whether they interact in a specific temporal sequence; or whether origins can be subdivided into distinct functional domains. The specific biochemical steps in DNA chain initiation and how they are catalyzed are also discussed. This book is organized into six sections and comprised of 41 chapters. The discussion begins by analyzing the replication origin region of the Escherichia coli chromosome and the precise location of the region carrying autonomous replicating function. A genetic map of the replication and incompatibility regions of the resistance plasmids R100 and R1 is described, and several gene products produced in vivo or in vitro from the replication region are considered. The sections that follow focus on the DNA initiation determinants of bacteriophage M13 and of chimeric derivatives carrying foreign replication determinants; suppressor loci in E. coli; and enzymes and proteins involved in initiation of phage and bacterial chromosomes. The final chapters examine the origins of eukaryotic replication. This book will be of interest to scientists, students, and researchers in fields ranging from microbiology and molecular biology to biochemistry, molecular genetics, and physiology.

The HittiteEtymological Dictionary is a comprehensive compendium of the vocabulary of Hittite, one of the great languages of the Ancient Near East, and of paramount importance for comparative Indo-European studies. Since the start of publication, as evidenced by frequency of reference and quotation, this work has become an important tool for study and research in Hittite, Ancient Anatolian, and Indo-European linguistics.

Eukaryotic DNA Replication: A Practical Approach is a comprehensive practical manual, with each of its eleven chapters describing an aspect of the methods currently used to investigate DNA replication in eukaryotes. The sequence of the chapters corresponds roughly to the order of events during DNA replication. The first chapters are concerned with initiation, looking at methods to characterize origins of replication and the proteins that interact with them. There then follow chapters describing protocols for the study of the elongation phase and the synthesis of the telomeres. The final chapters provide a more general overview of the study of DNA replication - including its investigation in model systems such as yeast, xenopus and viruses, and looks into methods used to study DNA:protein interactions that could be applied to the study of replication proteins. This exciting new volume provides over 120 tried and tested protocols for the analysis of eukaryotic DNA replication and will be of major interest to a wide variety of molecular and cell biologists, biochemists and medical researchers.

DNA replication is a fundamental part of the life cycle of all organisms. Not surprisingly many aspects of this process display profound conservation across organisms in all domains of life. The chapters in this volume outline and review the current state of knowledge on several key aspects of the DNA replication process. This is a critical process in both normal growth and development and in relation to a broad variety of pathological conditions including cancer. The reader will be provided with new insights into the initiation, regulation, and progression of DNA replication as well as a collection of thought provoking questions and summaries to direct future investigations.
