Learning objectives
Gli obiettivi del corso sono: (1) fornire le conoscenze necessarie alla comprensione della struttura e della funzione delle principali biomolecole costituenti gli organismi viventi; (2) descrivere i principali processi biologici presenti nelle cellule animali, con particolare riferimento a quelli coinvolti nel metabolismo delle molecole di origine alimentare; (3) fornire conoscenze necessarie alla comprensione del ruolo e della funzione delle macromolecole informazionali e delle principali metodologie di base inerenti la tecnologia del DNA ricombinante; (4) fornire le nozioni teorico-pratiche necessarie per la esecuzione pratica di semplici saggi colorimetrici.
