From: G-quadruplexes may determine the landscape of recombination in HSV-1
CD spectroscopic analysis of G4-motifs in flanking regions of breakpoints. The spectral signatures of the 8 oligomers chosen from the flanking sites of recombination breakpoints indicate the formation of G4 structures. Oligomers 1,3,4,5, and 7 form G4 s with parallel topology, while oligomers 2,6,8 form G4 s with hybrid topology. (The sequence of the oligomers 1–8 are provided in Additional file 1: Table S2)
