The sentence that I wrote was ambiguous, and you found an unintended (albeit interesting) meaning in it. WK took that and ran with it--turned out pretty interesting.
Anyway, my intended meaning was MUCH less interesting. I've changed it in the original post.
Or to determine that there are no proteins being transcribed from this sequence in another way.
now changed to
Or to determine, in another way, that there are no proteins being transcribed from this sequence.
I gave 'knocking out the gene' as one example to determine that no proteins are being transcribed from some gene. With the sentence above, I was just trying to say "I don't know all the ways we can determine that no proteins are being transcribed from a single gene."
Yes, I'm sweeping through my old threads. So no need to follow up. Just thought it's good to clear it up. Thanks for picking up on the ambiguity, I learned something about transcription that I didn't know before.
