Enter your answer in the provided box. Given two complementary strands of DNA containing 1.01 X 102 base pairs each, calculate the ratio of two separate strands to hydrogen-bonded double helix in solution at 3.49 x 10² K. (Hint: The formula for calculating this ratio is e-SE/RT, 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 102...
