MOLECULAR BIOLOGY

Course objectives

General expected learning outcomes The course provides an overview of modern molecular biology and basic technologies for the manipulation of DNA. The course objective is to acquire knowledge of the molecular mechanisms that allow the maintenance, regulation, and expression of the genome. These skills play an important role in the research and development of new drugs, and applications in biotechnology and biomedicine. Specific expected learning outcomes 1. Knowledge and understanding Knowledge of nucleic acids structure and functions. Knowledge of the molecular mechanisms of DNA replication, repair, transcription and protein synthesis, as well as the regulation of these processes. Basic knowledge of the main techniques of nucleic acid manipulation, the expression of recombinant proteins and the generation of OGM. 2. Applying knowledge and understanding Understanding of the molecular processes that control gene expression and regulation, underlying cell growth, division, and differentiation, and which are targets for the action and development of pharmacologically active agents. Familiarization of students with the experimental approaches used in molecular biology. 3. Making judgements Students will be invited to ask questions and analyse the topic under discussion so to acquire/perfect their proactive and critical attitude also using skills and knowledge acquired during previous courses. 4. Communication skills Describe and relate critically the processes studied. 5. Learning skills Read scientific articles in the field of molecular biologic and gain a critical understanding of their contents.

Frequency
Although optional, the teacher advises an active frequency for the achievement of the educational objectives of the course.
Exam mode
Talk at the end of the course aimed to evaluate the level of knowledge of basic molecular biology. To pass the exam, the student must demonstrate that he or she has at least acquired sufficient knowledge of the structure of the nucleic acids and of the cellular processes involving them (replication, transcription and translation). To achieve scores above the minimum the student must demonstrate a greater degree of knowledge of all the topics covered in the course and be able to connect them in a logical andconsistent way, with language properties.
Lesson mode
Lessons in class for 64 hours according to the schedule defined by the Board of the Study Course, of which 40 provided by the teacher Fabio Altieri.
