Training objectives
- Knowledges: most used molecular biology technology employed in genetic engineering and for the production of recombinant DNA. The second training objective is to describe biochemical and molecular biology technologies for the study of gene expression. A third objective is to describe the mechanism of action of biotechnological drugs based on DNA molecules.
Skills: ability to perform basic experiments of applied cell biology, biochemistry and molecular biology of nucleic acids and macromolecules of biotechnological interest. Ability to update the knowledge on the development of new therapeutic approaches.
METHODOLOGIES FOR THE TEACHING OF BIOCHEMISTRY AND APPLIED BIOCHEMISTRY

B. Description of the most important discoveries in the field of biochemistry, applied genetics, genetic engineering, molecular biology.
C. Methods and technologies for the study of biochemistry and applied biochemistry with respect to society, environment, health, biotechnology.
D. Teaching and learning processes in respect to digital technologies, e-learning and multimedia platforms.
D. I livelli di disseminazione e divulgazione degli argomenti attinenti alla biochimica applicata.
E. Teaching methodologies for the improvement of specific definitions in the field. Prerequisites
- The student should be expert in the following fields: structure and functions of proteins, DNA, RNA; DNA replication; transcription and splicing; protein synthesis.

- The course is organized with lectures (48 hours) on the program topics. The course objective is not only to teach the student the cultural bases of the course, but also teach the "know-how" through laboratory classes and lectures that, also using video as a teaching material, allow you to have the visual perception of the experiments that they are performed in biochemical studies and molecular biology applied to the development of new drugs and therapeutic approaches.
For the FIT project:
The critical discussion of the most important methods for the construction of teaching in the biochemistry field will be based on experimental approaches and observation of natural phenomena. This parte of the course will be performed with multimedia platforms. Learning assessment procedures
- Oral examination. The aim of the oral examination is to test the level of knowledge and deepening of the topics of the course program and the reasoning skills developed by the student on issues related to molecular diagnosis based on applied biochemistry and molecular biology. Generally, three arguments are asked, to which, in order to obtain the minimum grade, it is necessary to exhaustively respond. For each question 10/30 are attributed. The oral examination may finish also with one only question, if the commission verifies serious deficiencies of basic topics of the course. The overall evaluation is expressed in thirtieths (minimum grade 18).
