When heated, the DNA double helix separates into two random-coil single strands. When cooled, the random coilsreform the double helix.
a) What is the sign of the change in entropy (ΔS) for theforward process? Why?
b) Energy must be added to overcome H bonds and dispersion forves between the strands. What is the sign of ΔG for theforward process when TΔS is smaller than ΔH?
c)Write an expression that shows T in terms of ΔH andΔS when the reaction is at equilibrium. (This temperature iscalled the melting temperature of the nucleic acid.)
