Course program
Main goal of the course is to give to the students a general view of the molecular mechanisms which are at the base of the biological processes. For each argument a methodological section will introduce the students to the main technical approaches used at the state of the art. Practical training (2 CFU) will make the students to breath the atmosphere of a molecular biology laboratory. Particular attention will be given to the high throughput methods utilized in “Omic” approaches to the comprehension of biological processes.
General aims:
The course is focused on the deep connection between DNA and protein structure and their functions. The student will learn the molecular mechanisms which are at the base of the processes of Replication, Recombination, Transcription, DNA repair, RNA processing and splicing, protein Sythesis and their regulatory circuits.
Specific aims:
1. Knowledge and understanding: The student should learn the basic molecular mechanisms of the cellular omeostasis and gene regulation and the most used techniques of Molecular Biology.
2. Ability to apply Knowledge and understanding: The student should be able to apply this knowledge in the discussion of recent arguments of general interest in Molecular Biology research.
3. Critical Judgement abilities: The student should demonstrate critical judgement abilities in solving problems related to theoretical and practical Molecular Biology projects and should communicate his conclusions to the colleagues and to the teacher in an effective way.
4. the student should demonstrate to be able to apply the learned concepts to his future work in molecular biology.
