A variety of molecules physically bind to DNA by intercalation or insertion between the base pairs. The intercalation of chlorobenzylidine (CB) to calf thymus DNA was studied by circular dichroism spectroscopy [Zhong, W., Yu, J.-S., Liang, Y., Fan, K., and Lai, L., Spectrochimica Acta, Part A, 60A (2004): 2985]. Using the following representative binding data, determine the binding constant (K) and the number of binding sites per base (N)
