Mussel Glue

From the mussel link--

Another major barrier in bacteria lies in the structure of the gene encoding the adhesive protein. This is a long and extremely repetitive piece of DNA, and bacteria, correctly, recognise it as foreign and rapidly eliminate it through a process known as recombination.

Thanks for that link. It's pretty amazing glue that the mussels produce. I remember prying them off of the rocks as a kid and it was really tough.
