I never said that GTTACA was a word... quite the contrary. That is not what they are talking about when they mention the full length word for DNA. That is NOT any particular DNA strand.
And even if you do not like DNA, the word mentioned at the beginning of this thread must be a word if tetrachloride is a word, because they are exactly the same thing, the word-representation of a chemical. They convey exactly as much meaning as "dog," "mouse," "puke," etc. convey, that of a noun.
