Description of Research Expertise
2bb We are interested in understanding on a structural and biochemical level how DNA and RNA molecules are maintained and processed by living cells. In addition to the mechanisms and regulation of genome replication and transcription, this includes processes such as DNA repair, site-specific and homologous recombination, transposition, condensation of chromosomes, chromosome pairing and segregation, and RNA trafficking and splicing. Our approach is to establish three-dimensional models of macromolecular assemblies relating to a particular biological question using X-ray diffraction methods and to then develop mechanistic and functional models that can be tested experimentally.e 29
