Inference in biological systems

The course provides an introduction to molecular biology and to quantitative methods that can be used to extract information from complex biological systems, including the analysis of DNA, RNA and protein sequences, the reconstruction of phylogenetic trees, and the use of machine-learning techniques to analyze the structure of gene and protein networks.

Inference in biological systems

The course provides an introduction to quantitative methods allowing to extract meaningful information from complex biological systems. These include the analysis of DNA, RNA and protein sequences, the reconstruction of phylogenetic trees, and the study of the cell inner workings via quantitative models of gene regulation, cell compartimentalization and metabolism.

Inference in biological systems

• understanding basics notions of molecular biology; • understanding basic approaches to sequence alignment; • being familiar with structural inference and maximum entropy techniques; • being able to code simple sequence-alignment algorithms; • being able to apply basic machine-learning methods to given genetic and biological problems.

Inference in biological systems

Students will become acquainted with basic notions of molecular biology, probabilistic approaches to sequence alignment and inference of protein structures, and physical modeling of cell functions.

Inference in biological systems

Basics of probability theory, principles of statistical physics, basic programming skills (any language).

Inference in biological systems

**Modalità di esame:** Prova orale obbligatoria;

Inference in biological systems

The oral test will consist of 2-3 broad questions on the main topics of the lectures. The individual project will consist of the application of computational and machine-learning techniques to a given biological problem, and will be presented as ppt slides in an oral discussion. The grading of the project will contribute to 1/3 of the overall assessment.

Inference in biological systems

**Exam:** Compulsory oral exam;

Inference in biological systems

The oral test will consist of the in-depth presentation of a scientific work chosen by the Student among those discussed in the course and uploaded in the 'Material' section of the course site (or among other works otherwise related to the topics of the course), and of 2-3 broad questions on the main topics of the lectures. The grading of the presentation will contribute to 1/3 of the overall assessment (the maximum grade being 30L). The purpose of the exam will be to verify the Student's understanding of basic notions of molecular biology, probabilistic approaches to sequence alignment and inference of protein structures, and physical approaches to the modeling of cell functions.
