brominated poly[d(GC)].poly[d(GC)]
brominated poly[d(gc)].poly[d(gc)]
A double-stranded DNA polynucleotide consisting of two complementary strands consisting of repeating units of brominated guanosine and deoxycytidine residues, all residues in each strand being connected by 3'→5' phosphodiester linkages. The sites of bromination are at C-8 of guanine and C-5 of cytosine, although not all these sites are brominated, with bromination at the guanine C-8 predominating.
