Given two complementary strands of DNA containing 1.02 x 102 base pairs each, caleulate the ratio of two separate strands to hydrogen-bonded double helix in solution at 2.86 x 102 K. (Hint: The formula for calculating this ratio is eAEIRT, where AE is the energy difference between hydrogen-bonded double-strand DNAs and single-strand DNAs and R is the gas constant.) Assume the energy of hydrogen bonds per base...
