Abstract

The utility of formamide in the denaturation and renaturation of DNA has been examined. The mmelting temperature of duplex DNA is lowered by 0.6°C per per cent of formamide. The depression of melting temperature is independent of the GC content. Formamide also increases the width of the thermal transition. Upto 30% it does not affect the rate of DNA reassociation.
