RNAs often exhibit a high degree of conformational dynamics and heterogeneity, leading to a rugged energy landscape. However, the roles of conformational heterogeneity and rapid dynamics in molecular recognition or RNA function have not been extensively elucidated. Ultrafast time-resolved fluorescence
