Single-stranded complex guanine-rich DNA sequences from chromosomal telomeres and else-where can associate to form stable parallel four-stranded structures termed G4-DNA by a process that is anomalously dependent on the particular alkali metal cation that is present. The anomaly, which is not found in the formation of G4-DNA by oligonucleotides containing… CONTINUE READING
