The student must acquire some basic elements of molecular biology and must learn to apply the techniques of statistical physics to some problems from the equilibrium and nonequilibrium physics of biological systems, mainly in the field of biopolymers.

Kinetics of phase transitions: thermodynamics of interfaces, metastability and classical nucleation theory, domain coarsening, phase ordering with or without conservation laws (12 hours). Introduction to molecular biology: the cell; small molecules; proteins and nucleic acids. (4 hours).

DNA melting: experiments, zipper model, Poland-Scheraga model (7 hours). The helix-coil transition. Polymer collapse: Flory's theory. Collapse of semiflexible polymers: lattice models and the tube model. The self-avoiding walk and the O(n) model. (6 hours). An introduction to protein folding and design. RNA folding and secondary structure. Protein and RNA mechanical unfolding (15 hours). Molecular motors (6 hours).

Frontal lectures, using mainly slides for discussing biological facts and experimental results, mainly blackboard for discussing models and solving problems. Problems are proposed after completing each topic and then solved after a few lectures, so that students have time to try and find their own solutions.

ModalitÓ di esame: Prova orale obbligatoria;
The exam is based on an oral test, to be carried out in the PoliTO Virtual Classroom environment (in case of specific issues with the student's devices, use of other platforms will be attempted). The test typically involves questions on 2-3 topics, the first one being chosen by the student. The ability of the student to apply the techniques of statistical physics to problems from the physics of biological systems is tested by asking to discuss models of biopolymers and the relationship of their predictions to phenomenology.
