Aims/Description: TThe module examines in detail the mechanisms that maintain genome integrity and generate genetic variation, both of which are essential to eukaryotic life. The lectures illustrate how preventing and creating changes in DNA make use of the same biochemical machinery. The main emphasis is on eukaryotes, reference is made to prokaryotes mainly as an aid to understanding the importance of conserved processes. Mechanisms studied in detail include single-strand break repair, protein-linked DNA break repair, homologous and non-homologous recombination, avoidance of replication errors, mismatch repair, excision repair and mutagenesis. Throughout the module experimental detail is included to illustrate how conclusions on gene function and interactions have been determined.
