the same treatment extracts several other endonuclease activities : the two mg2+-dependent endonuclease activities cleaving double-stranded dna at ph 7.5 and 5.4 respectively , the ethidium-bromide-stimulated endonuclease activity , the endonuclease activity cleaving single-stranded dna at ph 7.l5 [ jacquemin-sablon et al . ( 1979 ) biochemistry , 18 , 119-127 ] , and a manganese-stimulated deoxyribonuclease activity cleaving double-stranded dna at ph 7.5 which has been discovered during the present work .
