For an abstract single‐stranded RNA, a combinatorial analysis is given for two important structures, hairpins and cloverleaves. The number of possible hairpins is O (2 n ), while the number of possible three‐petal cloverleaves is O ( n 3 2 n ), and the number of possible general cloverleaves is O ((2.21) n ).
