Learning outcomes

Fornire agli studenti le conoscenze di base dei meccanismi molecolari inerenti la trasmissione, la variazione e l’espressione dell’informazione genetica.
Alla fine del corso gli studenti avranno acquisito le nozioni fondamentali per la comprensione dei meccanismi molecolari del funzionamento cellulare in organismi procariotici ed eucariotici.

Syllabus
