DESCRIPTION:Nucleus of a living cell houses a cell genome - a polymer call
 ed chromatin\, which is a functional form of DNA.&nbsp\; It is very long\,
  e.g.\, 2 meters long for every human cell.&nbsp\; Nucleus is also an aren
 a of incessant energy-driven activity.&nbsp\; Experiments show that chroma
 tin undergoes large\, several micron\, scale motions sustained over long t
 imes of order seconds.&nbsp\; In the talk\, after reviewing the phenomenol
 ogy\, I will show how these flows may arise due to a phase transition in w
 hich chromatin-driving motors\, such as RNA polymerase\, form a polar ("fe
 rromagnetic") order.&nbsp\;
