The two strands of the helix-shaped DNA molecule are held together by electrostatic forces as shown in the Figure 16-44 in the textbook. Assume that the net average charge (due to electron sharing) indicated on H and N atoms is 0.2e and on the indicated C and O atoms is 0.4e. Assume also that atoms on each molecule are separated by 1.0 × 10-10 m Part A Estimate the net force between a thymine and an adenine. For each bond (red dots) consider only the three atoms in a line (two atoms on one molecule, one atom on the other). Express your answer using two significant figures. Π| ΑΣΦ ? FA-T = Submit Request Answer Part B Estimate the net force between cytosine and a guanine. Express your answer using two significant figures. IVE ΑΣΦ ? FC-G = N N
Part C Estimate the total force for a DNA molecule containing 105 pairs of such molecules. Express your answer using one significant figure. 15| ΑΣΦ www ? Hey Ftotal N
