In the Watson-Crick model for the DNA double helix (B form) the A-T and G-C base pairs share all but one of the following properties. Which is the exception? None of the proton-binding groups in the purine and pyrimidine bases is in its charged or ionized form. The plane of the base pair is roughly perpendicular to the axis of the helix in each case. The number of hydrogen bonds formed between the two bases of the base pair is the same. The distance between the two glycosidic (base-sugar) bonds is the same in both base pairs, within a few tenths of an angstrom.

The formation of a double-stranded structure must obey the rule that adenine hydrogen bonds to thymine (or uracil in RNA) and cytosine hydrogen bonds to guanine. Discuss reasons why complementarity is an important feature of DNA and RNA structure and function.
if this DNA has a molecular weight of 1.20 ×108 Dalton which contains a head in a about 200 nm long. Calculate the length of the DNA assuming the molecular weight of a nucleotide pair is 600 Dalton and assume that the DNA is a B-form and that there are 10 base pair per turn which makes is 34 Å per turn. ( 1nm = 10Å)
The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure below shows the bonding of thymine and adenine. Each charge shown is +e or - e, and the H-N distance is 0.110 nm. (a) Calculate the net force that thymine exerts on adenine. Is it attractive or repulsive? To keep the calculations fairly simple, yet reasonable, consider only the forces due to the O- H-N and the N-H-N combinations, assuming that these two combinations are parallel to each other. Remember, however, that in the O-H-N set, the O- exerts a force on both the H+ and the N-, and likewise along the N–H-N set. (b) Calculate the force on the electron in the hydrogen atom, which is 0.0529 nm from the proton. Then compare the strength of the bonding force of the electron in hydrogen with the bonding force of the adenine-thymine molecules (H (H (H)…
