All this stands fine with me, except we have to account for RNA that are 
other than mRNA, but that's easy: rRNA, tRNA, etc. The "cRNA" term 
required, for example, in some quantitative RT-PCR procedures (RNA 
complementary to a usually mutated cDNA) will continue to be a mind bender, 
but I think it still can fly.
