This volume contains edited contributions from the speakers at the NATO Advanced Research Workshop on "DNA Repair Mechanisms and Their Biological Implications in Mammalian Cells" held October 1-6, 1988, at the Abbaye Royale de Fontevraud, Fontevraud France. The meeting was dedicated to Paul Howard-Flanders (Yale University, New Haven, CT., 1919-1988), whose seminal con- tributions to the DNA repair field include the cO-discovery of the excision repair pathway, the elucidation of post-repli- cation repair in E. coli, the isolation of the lexA and recC mutants, and his extensive work on the...
