The course starts with the basic principles of recombinant DNA illustrating the mechanism of action of of restriction and modification enzymes, and gene cloning through host-vector systems.
The mechanism of action of standard and quantitative PCR is presented in detail, but particular importance is given to applications of such methodologies, through specific examples.
Among the different methods of DNA sequencing only the Sanger method is reported, both in its manual and automated versions.
The various techniques of analysis of nucleic acids and proteins, including electrophoresis on agarose and polyacrylamide and through blotting (Southern, Northern and Western blotting), and the different fields of application of these techniques are presented.
In regard to libreries, both the construction process, and the analysis of the genomic, cDNA and expression libraries are shown, with an emphasis on information obtained from their use.
The Arabidopsis thaliana and Homo sapiens genome projects are presented, explaining the criteria of choice of model organisms, and information obtained by the complete knowledge of these genomes.
Structural, functional and comparative genomics, as well as the technologies related to each of these branches, are presented. In particular, technologies related to structural genomics, through analysis of the genomic libraries for the sequencing of extended portions of DNA, and to functional genomics, through the main techniques of analysis of transcriptome and proteome, are explained.
Finally, genetically modified plants are presented: how they are realized through the two main systems (biolistic and Agrobacterium), by illustrating advantages and disadvantages of both these methods and how a genetic construct for expression in plants is made

Practical classes:
• Bacterial transformation using a recombinant plasmid vector, which is extracted in a subsequent practical class and characterized by agarose gel electrophoresis
• Standard PCR to determine the presence of a specific transgene in plants of GM wheats

If the students are more than 25, practical classes are performed in turns.
