|a The emphasis on mechanisms and the relationship between structure and function targets the chapters towards biochemists and biological chemists as well as molecular and cell biologists. The book highlights new insights into the replication process, from the assembly of pre-replication complexes, through polymerisation mechanisms, to considering replication in the context of chromatin and chromosomes. It also covers mitochondrial DNA replication, and includes archaeal paradigms, which are proving increasingly relevant to the study of replication in higher eukaryotes. Exciting potential drug targets in DNA replication are discussed, particularly in the context of treating malaria and cancer

|a Conversely, ageing may be associated with loss of replication activity and restoring it to cells may moderate some of the diseases associated with old age. Replication is, therefore, fundamental to a huge range of molecular biological and biochemical applications, and provides many potential targets for drug design. The fast pace of replication research, particularly in providing new structural insights, has outdated the majority of available texts. This learned, yet accessible, book contains the latest research written by those conducting it. It examines conserved themes providing a biological background for biochemical, chemical and pharmaceutical studies of this huge and exciting field. Rather than simply "itemising" the replication steps and the proteins involved, replication is tackled from a novel perspective. The book provides logical groupings of processes based upon biochemical similarities.

|a Written by leading experts, this learned but accessible book highlights the latest work on eukaryotic DNA replication, DNA replication, the process of copying one double stranded DNA molecule to form two identical copies, is highly conserved at the mechanistic level across evolution. Interesting in its own right as a fascinating feat of biochemical regulation and coordination, DNA replication is at the heart of modern advances in molecular biology. An understanding of the process at both the biological and chemical level is essential to developing new techniques in molecular biology. Insights into the process at the molecular level provide opportunities to modulate and intervene in replication. Rapidly dividing cells need to replicate their DNA prior to division, and targeting components of the replication process is a potentially powerful strategy in cancer treatment.
