AIMS AND CONTENT

LEARNING OUTCOMES

The course is part of the Integrated Course: “Biochemistry-Applied Biochemistry”. The educational objective of the course is to present and critically discuss the most advanced techniques used in biochemical research, a research-based discipline, and their main applications. The course will enable the student to understand the general criteria of biochemical experimentation, biological materials, principles, and equipment used for preparative and analytical purposes in the biochemical laboratory. The course content is constantly updated to render students familiar with the analytical approach to the various problems encountered in modern research laboratories, both basic and applied.

AIMS AND LEARNING OUTCOMES

The course aims to provide students with the basics of the main biochemistry and molecular biology techniques utilized in basic and applied research laboratories. The most modern biochemical methodologies are presented and critically discussed with the educational aim of providing knowledge of techniques useful in the separation, identification, and analysis of biomolecules for research and applied applications. The course content is constantly updated. The students' learning outcomes will be the theoretical knowledge and understanding of the main biochemical techniques and the ability to expound on them and identify their applicability in solving problems typical of biochemical laboratories with language property.

TEACHING METHODS

The course consists of classroom lectures. The lectures are developed with the support of computer-based material and, as far as possible, organized in a participative manner.  Supporting and in-depth materials (ppt presentations with exhaustive images and films on the techniques exhibited, links to sites of interest, bibliography, etc.) will be made available on Aulaweb.

Any Student with documented Specific Learning Disorders (SLD), or with any special needs, shall reach out to the Lecturer(s) and to the dedicated SLD Representative in the Department ( Prof. Luca Raiteri, Luca.Raiteri@unige.it ) before class begins, in order to liaise and arrange the specific learning methods and ensure proper achievement of the learning aims and outcomes. VERY IMPORTANT: any request for compensatory tools and adaptations in the exam MUST be done within 10 working days before the date of the exam according to the instructions that can be found at https://unige.it/disabilita-dsa/comunicazioni
