Task: Please create a description for a molecule.
SMILES: Nc1nc2c(nc(Br)n2[C@H]2C[C@H](OP(=O)(O)OC[C@H]3O[C@@H](n4cc(Br)c(N)nc4=O)C[C@@H]3O)[C@@H](COP(=O)(O)O)O2)c(=O)[nH]1.Nc1nc2c(nc(Br)n2[C@H]2C[C@H](OP(=O)(O)OC[C@H]3O[C@@H](n4cc(Br)c(N)nc4=O)C[C@@H]3O)[C@@H](COP(=O)(O)O)O2)c(=O)[nH]1
Constraint: Answer the question with full sentences.
Result: The molecule is 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. It contains a brominated poly[d(GC)].
