Course unit structured in the following modules:

Learning objectives

At the end of the course the student should have acquired sufficient knowledge and information to understand, critically discuss the biological strategies and interdependence goals between the various phases of metabolism and practically apply the molecular basis of the mechanisms of transmission of genetic information.


The student must have basic knowledge of the general and organic chemistry of the
main biological molecules. Basic knowledge of the biology of the
eukaryotic cell.

Course unit content

The course aims to provide a knowledge of metabolic pathways and their integration and the molecular
mechanisms of the transmission of genetic information.

Teaching methods

During lectures (face-to-face / in streaming), teacher will illustrate and discuss the different topics of the program. Students' reception for clarifications and exercises only by appointment (face-to-face or using Teams).

Assessment methods and criteria

The assessment of the achievement of the objectives of the course consists of an oral examination.
In the case of coronavirus emergency, the exams will be performed with oral test online using Teams platform.
