"The Physics of Confined DNA"
ABSTRACT:
DNA in viruses and in cells is packed in spaces much smaller than its natural size. This state of confinement places interesting constraints on a variety of biological processes DNA is involved in, such as viral infection, gene expression, and recombination. Quantitative experimentation using techniques such as laser tweezers, cryo-electron microscopy and fluorescence spectroscopy has recently begun to probe in detail the confined state of DNA, both in living cells and in the test tube. In this talk I will describe this emerging experimental landscape and outline the theoretical challenges it poses. The particular examples I will focus on will be provided by DNA packing in viruses and gene regulation in bacteria.
