The course of Applied Biology aims at providing students with basic knowledge in:
1. The characteristics of life
2. The molecular composition of cells
3. Structure and properties of prokaryotic and eukaryotic cell, with focus on animal cells and subcellular structures involved in movement.
4. The flow of genetic information
5. Mitotic and Meiotic cell cycle, reproduction and development
6. Basic Genetics
This course will provide the basic knowledge of biology for the biological- and medical-related disciplines of the B.S. degree in Movement Sciences.
Expected learning outcomes:
o Knowledge and understanding
The student has to learn the basic structure of life, cell biology, molecular biology and the basic genetics.
o Applying knowledge and understanding
The student’ll apply knowledge to:
1. identify the structure and the function of cell and subcellular organelles
2. integrate knowledge
3. the comprehension of complex molecular mechanisms and of intra- and inter- specie cell to cell communications
4. the next courses in biological- and medical-related disciplines.
o Making judgements
The student has to gain the skills to select the appropriate scientific sources in order to make correct data integration and interpretation. At the end of the course, he’ll be able to easily identify and compare different cell structures, to explain their functions and the corresponding molecular mechanisms.
The student has to explain knowledge using a proper scientific language, thus demonstrating a full comprehension of the course topics.
o Lifelong learning skills
The student has to develop the appropriate learning method in order to easily improve and upgrade his skills/knowledge
