Question

Enter your answer in the provided box.
Given two complementary strands of DNA containing 1.07 ×10² base pairs each, calculate the ratio of two separate strands to hydrogen-bonded double helix in solution at 3.04 ×10² K. (Hint: The formula for calculating this ratio is e⁻Δ
^E/RT, where ΔE 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 ×10⁻² kJ/mol under laboratory conditions. This model is a simplification of reality.
