it is very likely that you are right. Basically, the experiment is simple:
divide your PCR reaction and treat one with a gel filtration febore you add
the REs. Then ligate and watch out what will happen.
But as even traces of polymerases tend to drive paranoid people crazy by
surviving gel filtration colums, you might kill your polymerases by adding
a little phenol to your pcr rxn before you begin the cleanup.
