Here, users may download older secondary structure model diagrams.

Many of these diagrams are outdated -- however, enough users have shown interest even in the outdated versions that we present them here, without warranty.

The diagrams appear in PDF format.

This page is organized by first molecule, then major phylogenetic group and/or cellular location.


Changes Between Older and Current Versions (16S and 23S rRNAs)

These diagrams indicate the changes required to update the core regions of older diagrams to the current model version.
