Learning outcomes

The course aims at providing the knowledge of biology, biochemistry and genetics necessary for the understanding of physiological and pathological processes related to health and disease of individuals in different life ages. Biological and biochemical knowledge will contribute to the acquisition of skills aimed at promoting the adoption of practices that improve people’s health and nursing care.
By the end of the course, students will have acquired:
- basic knowledge of organic chemistry and biochemistry on the structure-function relationships of the main classes of biological macromolecules, on the metabolic regulation at the molecular level and on the energy level changes associated to different biochemical pathways;
- knowledge of cellular and genetic biology related to the structural, functional and molecular characteristics of the cell; understanding of genomics knowledge applications to medicine.
This knowledge will allow to understand cellular processes common to all living organisms and in particular the basic mechanisms that regulate metabolic activity, reproduction and cellular interactions and the mechanisms of genetic disease transmission in humans.

Examination Methods

The exam consists of 2 written tests, one for each module, to be passed simultaneously, based on all the issues covered throughout the course. In order to gain access to the biology test, students must have first discharged any training debts relating to the minimum biology knowledge.
To pass the exam, students must get a positive evaluation in both tests in the same exam and a global score of not less than 18/30. The final mark (/out of 30) will derive from the weighted average over credits of each single test score. Students can retire or refuse the proposed score and take the whole exam later.
