Recombinant DNA methods are powerful, revolutionary techniques for at least two reasons.
First, they allow the isolation of single genes in large amounts from a pool of thousands or millions of genes. Second, the isolated genes or their regulatory regions can be modified at will and re-introduced into cells for expression at the RNA or protein levels. These attributes help to solve complex biological problems and to produce new and better products in the areas of health, agriculture and industry.
Both volume 154 and 155 include the descriptions of several useful new restriction enzymes and rapid methods for DNA sequence analysis, along with a number of other useful methods.

Uneasy Allies? offers a careful study of the cultural distance between Jews and Evangelicals, two groups that have been largely estranged from one another. While in the past, American Jews have been wary of accepting the support of would-be Evangelical Christian allies, changes have occurred due to the critical situation in the Middle East. Over the past few years, leaders in mainstream Jewish organizations have been more open to accepting Evangelical support but have also encountered new tensions. Alan Mittleman, Byron R. Johnson, and Nancy Isserman bring together a collection of critical essays that investigate how each group perceives the other and the evolution of their relationship together. This book focuses on the history of Evangelical-Jewish relations from the level of communal agencies to grassroots groups. While the essays document differences in worldview, ethos, and politics, they also highlight shared values and problems. These commonalities have the potential to broaden the relationship between the two communities. Uneasy Allies? is an illuminating book that will stimulate discussion among scholars of religion and politics and those interested in Jewish studies.

This book is based on the papers presented at the conference on "Mecha nisms of DNA Damage and Repair: Implications for Carcinogenesis and Risk Assessment," held at the National Bureau of Standards on June 2-7, 1985, This volume deals with mechanisms of DNA damage and repair at the molecular level; consequences of unrepaired or misrepaired damage, with major emphasis on carcinogenesis; drugs which bind selectively to altered and potentially damaging DNA sequences; and potential utilization of DNA damage as an endpoint for assessing risks of UV light, ionizing radiations, chemicals, drugs, and hazardous agents in foods. Because the induction of mutations by radiation and genotoxic chemicals has been observed to follow one-hit kinetics in some instances, it is generally assumed that any level of exposure to a DNA-damaging agent may increase the risk of genetic disease or cancer in an exposed population. At the same time, however, there is evidence that although the DNA of living cells is continually damaged by natural background radiation, free radicals, and other naturally occurring processes, most of the damage is normally repaired.
