Deskripsi

Some repressors down-regulate gene expression when they bind to a site up to 100 base pairs away from the nearest activator. Here, the authors show that this quenching-like repression can be achieved by the excluded volume effect when a DNA-bound protein alters the propensity of DNA to form a loop.
