87995 - PHYSICAL METHODS OF BIOLOGY

Conoscenze e abilità da conseguire

The course will focus on the physical laws that underlie life. At the end of the course the student will acquire a broad understanding of the relation between physics, chemistry, and biology. They will be able to use theoretical and computational methods to predict properties of biomolecules and advanced experimental methods currently available to investigate the relation between genotype and phenotype.

Contenuti

What is life? Can we understand life in terms of fundamental physical principles? The course focuses on the physical principle behind the emergent biological properties of biomolecules and computational and experimental methods to characterize them.

1) Biology, chemistry and physics; top-down and bottom-up approaches; fundamental physics laws and emergent biological properties; time and length scales.

2) Biological molecules: proteins, DNA, RNA, lipids and their environment.

3) Intramolecular and intermolecular interactions

4) Thermodynamics and statistical mechanics of chemical interactions and biopolymers; chemical and biomolecular kinetics;

5) Atomistic simulation as a computational microscope; molecular dynamics and Monte Carlo simulation; estimation of thermodynamic and kinetic properties; free energy methods.

6) Protein folding; physics-based and knowledge-based methods for protein structure prediction.

7) Experimental biophysics, with a focus on methods to investigate structure and dynamics of proteins (x-ray diffraction; NMR; cryo-EM; SMFS; FRET)

8) Stochastic processes (master equation, Markov processes)

9) Physics of brain
