Table 1 Characteristics of secondary structure predictions performed using the P-DCfold algorithm on a tmRNA alignment of 44 sequences and a RNaseP alignment of 54 sequences, when all possible combinations of 4 homologous sequences are considered (left) and when only combinations of 4 sequences among 10 homologous sequences initially selected by the common homology model M _HC are considered (right).
