In silico analysis of human HpaII/MspI fragments by length. The numbers of fragments computationally generated from the reference human genome sequence were plotted by length, demonstrating higher frequencies of shorter fragments. The three peaks observed (at 69, 135 and 204 bp) are due to the presence of Alu SINEs (mainly AluS and AluY), peaks that can also be observed in the ethidium bromide staining of the MspI reference representation in Figure 2 (b, c).
