Yes, the Titin example is completely ridiculous. On the one hand, the protein Titin is one of the longest sequences. However you can form a 'word' out of any protein or DNA (or other macromolecue or polymer) this way.

The key problem for me is that you would never refer to any polypeptide this way in a sentence. It would be like referring to a piece of software by concatenating its source code into one long 'word'. Meaningless.
