with of the fraction of G-C base pairs:


(a) Estimate the melting temperature of a DNA molecule containing 40.0 per cent G-C base pairs in both samples. Hint. Begin by plotting Till against fraction of G-C base pairs and examining the shape of the curve.

(b) Do the data show an effect of concentration of ions in solution on the melting temperature of DNA? If so

provide a molecular interpretation for the effect you observe.
