Abstract

This project used Atomic Force Microscopy (AFM) imaging to examine the effects of different intercalation conditions upon the elastic properties of intrinsically straight DNA molecules. Three intercalating molecules (chloroquine, ethidium bromide, and acridine) were used to demonstrate the dependence of persistence length and mean polymer extension on the intercalator type. It was found that all three intercalators significantly increased persistence length, and that this effect was most pronounced for ethidium bromide. In addition, an analysis of the normal bending modes of the static molecules corroborated these results. The only intercalator which resulted in significant extension of the DNA polymers was ethidium bromide. By measuring these properties for a model system of DNA, the understanding of binding effects of intercalators and the bending properties of generic DNA molecules will be improved.
