The word 'gene' is quite ambiguous, hardly worth even using

It's a stupid way of thinking. I define a gene as a DNA sequence
that is transcribed. (There are a few exceptions to this definition
but it works very well.) RNA editing and the rest don't have any
effect on my ability to recognize what I define as a gene.

You can try as many different definitions as you like but I think
I'll stick with one that works, thank-you very much.
