BIO Base pairing in DNA, II. Refer to the previous problem. Figure 17.47 shows the bonding of the cytosine and guanine molecules. The O—H and H—N distances are each 0.110 nm. In this case, assume that the bonding is due only to the forces along the O—H—O. N—H—N. and O—H—N combinations, and assume also that these three combinations are parallel to each other. Calculate the net force that cytosine exerts on guanine due to the preceding three combinations. Is this force attractive or repulsive?

- The foot of your average gecko is covered with billions of tinyhair tips—called spatulae—that are made of keratin, the proteinfound in human hair. A subtle shift of the electron distribution inboth the spatulae and the wall to which a gecko clings producesan adhesive force by means of the van der Waals interaction between molecules. Suppose a gecko uses its spatulae to cling to a vertical windowpane. If you were to describe this situation in terms ofa coefficient of static friction, ms, what value would you assign toms?
