Spectroscopic analysis reveals the effect of hairpin loop formation on G-quadruplex structures.

ABSTRACT: We study and uncover the effect of hairpin structures in loops of G-quadruplexes using spectroscopic methods. Notably, we show that the sequence, structure, and position of the hairpin loop control the spectroscopic properties of long loop G-quadruplexes, and highlight that intrinsic fluorescence can be used to monitor the formation of non-canonical G-quadruplexes.
