Il Nobel per la chimica 2020 è andato alla francese Emmanuelle Charpentier e alla statunitense Jennifer Doudna per il metodo che hanno sviluppato per modificare in modo preciso il codice genetico.
Come funziona il metodo sviluppato da Charpentier e Doudna
RSI Info 07.10.2020, 18:02
Le due ricercatrici hanno sviluppato delle "forbici genetiche" CRISPR/Cas9 in grado di andare a tagliare la molecola del DNA negli esatti punti desiderati. Lo strumento è stato sviluppato nel 2012 e da allora ha portato a scoperte in campi diversi, dalla biologia alla medicina.
La scoperta nasce dagli studi di Charpentier sugli streptococchi, durante il quale ha individuato una molecola fino ad allora sconosciuta, una sorta di "forbice genetica". In seguito ha cominciato a collaborare con Doudna con la quale è riuscita a ricreare e semplificare il sistema per intervenire sul DNA.
