Organisms with linear chromosomes have to solve the problem that DNA replication makes them shorter. This is due to the fact that DNA polymerase can only add bases to the terminal 3 -OH of a DNA chain. The DNA replication initiation complex uses RNA primers to provide the initial 3 -OH and to initiate lagging strand synthesis. While one strand can be copied all the way to the end of a chromosome, the other, lagging strand, must be primed at short intervals in order to provide a 3 OH group for DNA polymerase as the replication fork advances through a chromosome. The problem at the end of a chromosome then is that the lagging strand has nothing for the primer to bind to. Without some kind of solution, each replication cycle would result in a shorter chromosome.
At its meeting of 9 and 10 December 2020 and upon application of Joël Mesot, President of ETH Zurich, the ETH Board appointed 14 professors. They will work in a total of ten departments in a wide range of research areas. In addition, an ecotoxicologist was awarded the title of professor.
The new professors in brief:
Dr Pierrick Bousseau ( 1992), currently CNRS Research Fellow at the University of Paris-Saclay, France, as Assistant Professor of Mathematical Physics in the Department of Mathematics. Pierrick Bousseau conducts research in an area where algebraic geometry intersects with mathematical physics and symplectic geometry. He has a particular interest in enumerative geometry, which is concerned with counting geometric objects with given characteristics. Pierrick Bousseau has won several awards for his research. By appointing him, the Department of Mathematics is gaining a talented young mathematician with strong links to theoretical physics.
