sense versus anti-sense terminology

Dan,

Your life will become much simpler if you refer to the two DNA
strands as the "template" and "non-template" strands in the context 
of the transcription process which initiates gene expression. 
This terminology is so straightforward that it needs no explanation
-quite unlike the "sense" vs "anti-sense" or proposed "transcribed"
terminology.

As for the original coinage of the term "sense-strand", that would 
require some digging, much like determing the origin of a term like 
"fast lane", except perhaps a lot easier. :)

PS."Sense", "plus", "RNA-identical", "non-template" are all interchangeable,
much to the dismay of the student of molecular biology. The term "sense"
refers directly to the fact that this strand consists of a series of 
nucleotide bases which makes "sense" in specifying a string of proteins
via the universal genetic code. The other strand when read in context
of the genetic code would specify a peptide irrelevant to the gene of 
interest, or perhaps no peptide at all, due to base triplets specifing
peptide chain termination.

Let us know what you find.

Regards,

Jim
