The teaching is organized as follows:

Learning outcomes

------------------------
MM: BIOLOGIA APPLICATA E GENETICA
------------------------
The course purposes are: • To give basic knowledge about living organism characteristic: procariots, eucariots, viruses, through the acquisition of the fundamental concepts of biology and of the structural, functional and molecular principles of cellular processes. • To provide the basic knowledge on the fundamental concepts of genetics and transmission of hereditary characters.
------------------------
MM: BIOCHIMICA
------------------------
Basic knowledge of general and organic chemistry preparatory for biochemistry. Structure-function relationship of the most important biological macromolecules and of the metabolic regulation at the molecular level. Cross-talk between the different biochemical pathways and the energy level changes associated.
