Knots: from the sailing boat down to the cell's nucleus illustrated by means of simple experiments

Date: 
Thursday 23rd August 2012 - 11:30 to 12:30
Venue: 
INI Seminar Room 2
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
