The two strands for the helix-shaped DNA molecule are heldtogether by electrostatic forces as shown in class. Due to electron sharing, themagnitude of the net average charge on the H and N atoms, each, is 0.2e. Thenet average charge on the C and O atoms, each, is 0.4e. The distance betweenany two adjacent atoms on the same molecule is 0.1nm. Since electric fieldsdecrease as an inverse square law, they die off quickly with distance. So, theonly fields that really contribute to any given bond are due to the 3 atomsalong the red dotted line in the class diagram (two atoms on one'molecule andone atom on the other molecule).Calculate the electric fields and net force between a thymineand an adenine pair.=Calculate the electric fields and net force between a cytosineand a guanine pair.nConsider the OHN bond in the AT nucleotide. Can theelectric field be zero anywhere along the axis of this bond? If not,explain why not. If so, find where the electric field is zero.

Permutation is the ordered arrangement of m number items out of a list of n items. For instance, the DNA strand with sequence of 3 bases: G-A-C IS different w ith A-G-C, C-A-G, G-C-A, A-C-G, and C-G-A. From this, we have: P-3) 3! 3x2x1 Therefore, there are 6 dıfferent sequences of DNA strands that can be formed out of 3 given bases. In general, we have this formula for permutation: (n-m)!
