The overall goal of this thesis was to investigate the environmental conditions that induce i-Motif folding of the DNA strand DUX4L22, a cytosine-rich segment of DNA found in the human genome. Cellular conditions were simulated using sodium cacodylate buffer and multiple weights of polyethylene glycol as a crowding agent. The presence of i-motifs were confirmed by Circular Dichroism spectroscopy. I found that DUX4L22 does form i-motifs under these physiological simulations at both acidic and neutral pHs. DUX4L22 therefore shows potential for use in studies of a wide variety of biotechnological advances, such as regulatory switches in nanomachines or drug-delivery systems.
