I received several answers to my previous query about alternate
genetic codes and require no further information.
Thanks to the following individuals who kindly provided literature
Glenn A. Herrick
Francis Ouellette provided a soon-to-be released URL to web page at
NCBI containing both literature citations and the actual codes.
Please contact me via email if you would like me to send you the
citations that I've collected.
