Comparison of Type 1 events for i-motifs without tails and with two nucleotide tails on the 5′ and 3′ ends. The i–t traces represent 20 ms of two representative events. Data were recorded at −120 mV (cis vs trans) at 22 °C in 1.0 M KCl electrolyte solution buffered with 10 mM phosphate and 5 mM citrate at pH 5.0.
