Parallel-stranded linear homoduplexes of d(A+-G)n > 10 and d(A-G)n > 10 manifesting the contrasting ionic strength sensitivities of poly(A+.A+) and DNA.
In contrast to shorter homologs which only form a single-stranded nucleic acid alpha-helix in acid solution at [Na+]</=0.02 M Na+, d(A-G)20,30 form in addition a parallel-stranded duplex with (A+.A+) and (G.G) base pairs and interstrand dA+...PO2-ionic and dA+NH2... O=P H-bonds. Under conditions whe...
