Given our current understanding of nuclear structure, it is difficult to imagine how the nucleus performs its varied functions and controls the traffic of its many components. For example, how can densely packed chromatin be transcribed without the helical nature of the DNA resulting in entangled DNA and RNA and a stalled RNA polymerase? Here, Jacques Dubochet discusses a model of transcription in which DNA rotates around its axis, rather than RNA polymerase rotating around the DNA. Furthermore, he suggests that a view of chromatin as 'liquid' may help in understanding a wide range of nuclear functions.
