Figure 4.

Ω versus rank plot for all Inline graphic possible SS structures for L = 55 shown as (a) log–lin and (b) log–log plots. The black line is from the analytical approximation and the green squares denote the natural data. The horizontal red dotted-dashed line is Inline graphic near the peak of the PG(Ω) distribution for L = 55 in figure 3. The 13 L = 55 hammerhead ribozyme structures from the fRNA database (red squares) are clustered near this peak. The vertical blue dotted line in (b) denotes Inline graphic the ‘effective’ number of SSs. This set of Inline graphic of all structures captures the majority (≈75%) of natural structures.
