Distribution of mutations in Gram-negative eubacterial 5S rRNAs and significance for sequence analysis

Alignments of 70 5S rRNAs from Gram-negative eubacteria were used to derive a position-wise frequency distribution of mutations along the 5S rRNA molecule. These emperically derived, position-wise evolutionary trees. Significance of the distribution of mutations in the 5S rRNAs, prepared for the Gram-negative eubacteria, as well as its relationship to secondary structure, is discussed.
