The student will acquire skills related to the techniques for the analysis of the biochemical aspects of prokaryotes and eukaryotes and cell culture techniques, even on a large scale; for the study of the structure, functions and analysis of biological macromolecules and cellular processes.
Course Structure
Oral lectures integrated by laboratory activities.
Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
Learning assessment may also be carried out on line, should the conditions require it.

Learning Assessment
Learning Assessment Procedures
The evaluation of the knowledge acquired takes place through an oral exam. The grade is expressed on a scale of thirty, up to a maximum of 30/30 cum laude.
The following parameters will be taken into account to assign the final grade:
• Score 29-30 with honors: The student demonstrates in-depth knowledge of the topics, promptly and correctly integrates and critically analyzes the situations presented, independently solving even very complex problems. He has excellent communication skills and competently masters the scientific language adopted.
• Score 26-28: The student has a good understanding of the topics, is able to integrate and analyze the situations presented critically and logically, explains the topics clearly using appropriate scientific language.
• Score 22-25: The student has a fair understanding of the topics, even if limited to the main areas. He is able to integrate and critically analyze the situations presented, although not always in a linear way, and presents the topics quite clearly with moderate linguistic competence.
• Score 18-21: The student has minimal knowledge of the topics, has a modest ability to integrate and critically analyze the situations presented and presents the topics clearly enough, although his/her linguistic competence may be poorly developed.
• Exam not passed: The student does not have the minimum required knowledge of the fundamental contents of the course. The ability to use a specific language is minimal or non-existent and the student is not able to independently apply the knowledge acquired.
