The two strands of the DNA molecule are held together by hydrogen bonds between base pairs.When an enzyme unzips the molecu to separate the two strands, it has to break these hydrogen bonds. A simplified model represents a hydrogen bond as the electrostat interaction of four point charges arranged along a straight line. The figure shows the arrangement of charges for one of the hydroger bonds between adenine and thymine. Estimate the energy that must be supplied to break this bond. Hydrogen bond H 92 93 94 0.120 nm 0.180 nm 0.120 nm Adenine Thymine where q = -0.490e, q2 = +0.490e, q3 = -0.590e, and q4 = +0.590e. The energy that must be supplied to break the hydrogen bond is |J.
