ssu rRNA sequence stack replaces 16S/18S rRNA stack.  This stack was
rewritten from scratch & contains the entire Ribosomal Database
Project sequence release #1.  The sequences are accessable via a
series of linked phylogenetic trees, a list, or by name.

--------

16/18S rRNA seqs ("16/18S") is a Hypercard stack for the Apple Macintosh 
series microcomputer.  The stack is designed for use by scientists 
(molecular biologists in particular) for the storage & retrieval of non-
aligned small subunit ribosomal RNA sequences.  The current version of 
16/18S comes with 228 16/18S rRNA sequences from all three phylogenetic 
Kingdoms.  rRNA sequences are accessed through a series of linked 
phylogenetic trees; clicking at any terminal node of a tree will either 
take you one level higher (or lower) in the overall tree, or will 
present a menu of choices of rRNA sequences from the phylogenetic group 
represented by that node.  Sequences can be printed out or saved to 
either the clipboard or a MacWrite file.  A simple search capability is 
provided for locating sub-sequences.  16/18S will run on any Macintosh 
computer that can run Hypercard.  Hypercard 1.1 (or later) required.

The 16/18S rRNA seqs HyperCard stack is internally documented through 
the use of the HyperCard "?" button.  Internal help provides a 
description of all of the HyperCard buttons.  References are provided 
for each of the sequence entries.
