Abstract
The melting temperature for the d(AT)24.d(AT)24 stretch, located inside the DNA helix and terminally, have been determined in a wide range of ionic strength values (0.01 - 1 M Na+). The cooperativity factor was calculated from the shifts in the melting temperature of the stretch due to its different boundary conditions. With the sodium concentration decreasing from 1 M to 0.01 M the cooperativity factor dropped by three orders of magnitude, its change being less marked at high than at low ionic strength.Entities:
