[ECOLOG-L] mutation sentences

[Shelly Thomas]

Dear Colleagues,I am teaching a little bit of genetics to gen ed students.  
I am looking for a sentence made of three letter words to demonstrate codons.  
For example, "You can see the cat and dog eat all day and get too fat for the 
bed."  If you you insert or delete a letter, this is now a nonsense sentence.  
That is great for making one point.  
However, I would like a sentence that, if you insert or delete a letter (or two 
or four...all in one place, please... one indel), that it forms a whole new 
sentence that makes sense (or at least part of the sentence now makes sense) 
but means something entirely different.
Any suggestions?
Thank you,Shelly
