It was established that one half of the ledakrin (I-nitro-9-(3-dimethylaminopropylamino)-acridine) bound to the DNA in the cells of the studied onion root tips (Allium cepa L.), forms labile complexes with it, the remaining half is covalently attached to only one strand of the DNA. One molecule of covalently bound ledakrin falls on average to 104-2X104 pairs of bases
