Karl is absolutely correct. The experiment originally proposed should
lead to zero labelling.
Dominic, get some gamma ATP. Also, do yourself a favor and consult one
of the popular Mol. Biol. protocols books and/or a biochem. text to make
sure you understand the different ways to label "ends" of DNA.
