WebThe decrease of dT (m)/dX (G) (C) is a monotonic function of decreasing water activity in the salt solutions. We interpret this decreased composition dependence of the thermal stability of the various DNA's as being due to a destabilization of the GC base pairs relative to the AT base pairs by the concentrated salt media.
