BowmanResearch summary


Our lab is interested in how genetic material is packaged in eukaryotes and the implications this has for biological processes. Within each cell of our body, we have nearly four metres of DNA distributed over 46 chromosomes which is sequestered in a nucleus of only 1000 m3. Chromatin must, therefore, fulfil two conflicting roles: structure DNA so that genomic instability is minimised, but at the same time remain accessible to factors involved in transcription, replication and repair. In studying these contrary roles, our investigations span two length scales, namely the assembly of individual nucleosomes to form the 10 nm fibre and the mechanics of higher-order chromatin domains. To do this we utilise both in vitro biochemical approaches and advanced live-cell imaging.
