Estimates of the memory and time required to reconstruct ancestral structures of three RNAs from several families of biological interest (as reported by Indiegram).

The nanos 3′ translational control element (TCE) sequences are the seed sequences of the corresponding RFAM family [5] and the three tRNA sequences are from the BRalibaseII database [55] (identifiers AB042432.1-14140_14072, Z82044.1-16031_16103 and AC008670.6-83725_83795). The group II intron sequences (identifiers Z00044.1-87253_87177, X57546.1-2817_2907 and X04465.1-2700_2775) are from BralibaseII [55]. The Y RNAs are hY1, hY4, and hY5 from [104]; sequence lengths exclude the conserved stem S1. The time estimates are for a 2.2 GHz AMD Opteron 848 CPU.
