Voto Finale

The Course of Recombinant DNA technology is aimed at providing the students with the theoretical bases of recombinant DNA technology, coupled to a detailed knowledge of the underlying experimental approaches.
The expected learning outcomes for this course will be the following:
- Knowledge of the theoretical/operative know-how on the main methodologies for DNA manipulation-
- Ability to properly develop an experimental plan within the context of the current research in the fields of molecular genetics and molecular biology.
- Ability to achieve informed judgment, adequate expertise and communication skills in relation to the course content, and the skills required to develop and maintain issues related to the acquired knowledge, by means of critical reasoning and problem-solving attitudes.
- Ability to implement basic experimental protocols during laboratory classes and at the same time to develop a team-work attitude.

Four practical laboratory training lessons (4 hours each) will be held. The teaching module is focused on the planning and fulfillment of an experimental plan that wil include the following experiences:
- PCR-mediated analysis of the results of a molecular cloning experiment
- DNA extraction from bacterial clones and analysis by restriction enzymes digestions
- Gene transfer experiments in human cultured cells by means of transient transfection assays
- Validation of the transfection efficacy by realtime PCR gene expression analysis
- Further validation of the transgfection efficacy by fluorescence microscopy analysis

Recommended textbook: Watson/Caudy/Myers/Witkowski “DNA ricombinante” – Zanichelli. Other textbooks might be suggested for in-depth study. The teaching material is updated regularly and will be provided to all students in the e-learning online platform as Powerpoint slides file, short notes, animation files and articles from scientific literature on selected issues. “Brain training” questions will also be uploaded in the online platform.
