The following is a slightly dated table for Neurospora crassa, based  
upon 38 genes found in GenBank 63, as produced by J. Michael Cherry  
(cherry at frodo.mgh.harvard.edu) with the GCG program CodonFrequency.

Duplicates, pseudogenes, mutant and synthetic genes were not  
included. Coding regions were specified using the Feature Table of  
each entry, then checked for accuracy. If more than one stop codon  
was found the sequence was not included.
