Figure 1

Illustration of the construction of the stem-bulge-gap notation.

In the stem-bulge-gap notation at the bottom line, the symbols of ‘|’, ‘!’ and ‘:’ represent respectively the base pair of ‘CG’, ‘AU’ and ‘GU’, the symbols of ‘o’, ‘x’ and ‘-’ represent respectively the loop, bulge and gap. In the asymmetric bulges, the symmetric part is indicated with ‘x’ and the asymmetric part with ‘-’.
