Fig. 2From: P finder: genomic and metagenomic annotation of RNase P RNA gene (rnpB)Distribution of RNase P RNA structural classes by type and length. RNase P RNA has a broad diversity of sequence length and structure. A-type RNase P RNAs are the most common structural class. The minimal T-type, C-type, and M-type are uncommon with only 28 organisms identified to date with one of these structural classesBack to article page
