poly[d(tm(5)c)].poly[d(ga)]
A double-stranded DNA polynucleotide consisting of in one strand a repeating unit of thymidine and 5-methyldeoxycytosine residues, with in a complementary strand a repeating unit of deoxyguanosine and deoxyadenosine residues, all residues in each strand being connected by 3'→5' phosphodiester linkages.
