Given two complementary strands of DNA containing 1.08 x 102 base pairs each, calculate the ratio of two separate strands to hydrogen-bonded double helix in solution at 3.32 x 102 K. (Hint: The formula for calculating this ratio is e AE/R", 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 pair to be 7.70 x 10 kJ/mol under laboratory conditions. This model is a simplification of reality. Guide
