hmmmm...... autosequencer is that what they used to map the human genome? Is it really a word? Any opinions?

A quick Google search turns up slightly more hits on "AUTO SEQUENCER" (265) than the one word construct AUTOSEQUENCER (233), not that this proves anything at all.

I like your answer FallibleFiend. I'm just not sure it officially qualifies.

I have another word in mind for AUQ that is only 10 letters in length.
