CONTACT:Mustapha Amrani
DESCRIPTION: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 resis
 tance to traction and the unknotting of DNA knots by enzymes\n
