The processes of DNA repair and recombination are currently of widespread interest. This book, which arises from a Royal Society discussion meeting, presents an authoritative and very comprehensive overview of the subject by the leading researchers in the field. Key topics discussed include initiation, control and detailed mechanism of homologous recombination, V(D)J recombination and site-specific recombination, regulation and mechanisms of gene amplification and the role of nucleotide excision repair proteins in repairing DNA damage.
