Ab initio predictions for 3D structure and stability of single- and double-stranded DNAs in ion solutions
Fig 7
The comparisons of stability between predictions (lines) and experiments (symbols) for dsDNAs in monovalent/divalent ion solutions.
(A) The melting temperatures (Tm’s) as functions of [Na+] for three dsDNAs with sequences of (GCATGC)2, (GATGCGCTCG)2, (ACCCCGCAATACATG)2 from bottom to top, respectively. Symbols: experimental data [87,97]. Lines: predictions from the present model. (B) The melting temperatures (Tm’s) as functions of [Mg2+] for the dsDNA with sequence of (GCATGC)2 at different [Na+]’s: 0.012M, 0.15M, and 1M from bottom to top, respectively. Symbols: experimental data [87]. Lines: predictions from the present model.
