Seminar Room 2, Newton Institute Gatehouse

Abstract

Knots are pervasive in our daily life at the macroscopic level as well as at the microscopic level. With the help of some "experiments", I will present few important features of knots starting with macroscopic knots and then go into the cell's nucleus where knots play a role in the functioning of the DNA. Among the presented examples I will discuss some mathematical properties, the hydrodynamic behavior of knots, their resistance to traction and the unknotting of DNA knots by enzymes
