OVERVIEW

The course is aimed to give insight about regulatory mechanisms of gene expression in eukaryots and to provide information about the molecular biology techniques currently employed in diagnostic and research laboratories.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to equip the student with a basic knowledge of the structural and functional organization of eukaryotic genomes. The course covers the aspects related to the stability of the genomes, including the accuracy of the replication machinery,  the mechanisms of DNA repair and disorders related to their defects. Particular emphasis is dedicated to regulation of gene expression both in prokaryotes and eukaryotes. Information about the most common molecular biology techniques are provided.
