I asked Bruno Zimm what kind of DNA would stick in the wells, since
total E.coli and intact yeast chromosomes do not stick in wells, and he
said it must be something with more than 2 ends.
If the product has 3 or more ends, these ends will hang up on the
agarose and be unable to serpentate (I think that's the word).
That's all I have (or don't have, as the case may be).
