Ribosomal RNA genes sequences

Zardoya, R. et al.. Revised dinoflagellate phylogeny inferred from molecular analysis of large-subunit ribosomal RNA gene sequences, J. Mol. Biol. 41, 637, 1995. 

The third item on the locus line indicates the molecule type. The mol type usually is DNA or RNA, and it can also indicate the strandedness (single or double, as ss or ds, respectively) however, these attributes are rarely used these days (another historical leftover). The acceptable mol types are DNA, RNA, tRNA, rRNA, mRNA, and uRNA and are intended to represent the original biological molecule. For example, a cDNA that is sequenced really represents an mRNA, and mRNA is the indicated mol type for such a sequence. If the tRNA or rRNA has been sequenced directly or via some cDNA intermediate, then tRNA or rRNA is shown as the mol type. If the ribosomal RNA gene sequence was obtained via the PCR from genomic DNA, then DNA is the mol type, even if the sequence encodes a structural RNA.
