“…Recent work has suggested that chromatin structure can influence DNA repair in several different ways. Variations in reactivity of chromatin subfractions with alkylating agents have been shown (3)(4)(5). Nucleosome structure influences the removal of 3-methyladenine by a purified glycosylase (6), and protein nucleic acid interactions have been shown to mask pyrimidine dimers from UV endonucleases (7)(8).…”

“…Τό δλικδ κυτταροπλασματικό RNA διαλύθηκε σέ 1 δγκο διαλύματος πρόσδεσης καί προσετέθηκαν 9 δγκοι DMSO. 'Αμέσως μετά προστέθηκε 1 αρχικός δνκος ρυθμιστικού διαλύματος χλωριούχου λιθίου καί τδ δείνμα θερμάνθηκε στους 65 Συμπεραίνεται δτι ή αναστολή τής Hn-RNA σύνθεσης οφείλεται σέ λειτουργική αλλοίωση τής χρωματίνης.Ή αλλοίωση αυτή οφείλεται στην μεθυλίωση τής χρωματίνης. "Ετσι βρέθηκε ότι ή Ν,Ν-διμέθυλο-νιτρωδοαμίνη προκαλεί μεθυλίωση δλων τών χρωματινικών συστατικών (ίστόνες,μή ίστόνες,καί DNA).…”
