A pseudoknotted tRNA. Secondary structure of the yeast phenylalanine tRNA along with its dot-bracket representation [1]. The folding forms a pseudoknot because of the G-C pair at positions 18–50 and pair G-C at position 14–42. There are three multiloops (coloured in red) at the base of the three stems with hairpins
