Learning objectives

Genome sequencing has generated a huge amount of data which have revolutionized the research approach. the 'omic' concept has been applied to all field of genetic research with the aim to study the whole genome at structural and functional level. the objective of the course is to provide the knowledge of the basic principle of the new approaches in the field of biological and genetic analysis. Practical activities are not foreseen, however the students will have the opportunity to apply some of the approaches previously discussed, during the stage period. The case studies can be considered an opportunity to train the students in the critical analysis of research approaches.

Course unit content

The course is organized in two groups of lectures. The first group is focalized on “Molecular markers” and will give an overview of the most popular molecular markers used for DNA analysis. Protocols and associated problems will be described. Case studies will be described and discussed in order to give some examples of the main applications of molecular markers (genetic mapping, fingerprinting, marker-assisted selection, association mapping, locating and cloning genes for important traits, forensic sciences, positional cloning of disease genes). The second group of lectures will regard genomic analysis, in order to provide the knowledge about the characteristics of a genome in different types of organisms. The main steps of genomic analysis will be discussed (genetic mapping, physical mapping, genome sequencing, and annotation)
Case studies will be discussed about genomic characterization in model organisms. The discussion of case studies will allow the students to understand how molecular markers can be useful in genomic analysis.

Teaching methods

The course is organized in lectures, some practical activities in will regard the use of genomic database and literature database. This activity is instrumental for the preparation of the final exam.

Assessment methods and criteria

The learning ability will be verified with an oral examination based on: i) discussion of a scientific topic, chose by the student, taken from scientific literature; ii) general questions about the topics treated within the course. In this way the teacher will be able to evaluate the learning ability in general and the ability to apply the knowledge acquired to the understanding of the research approaches utilized in the genomic field.
