No, you aren't missing anything, I am. I made a big mistake here, no doubt.
I guess my memory has faded over the years; thanks for correcting me.
However, your response could have been a little more informative. Is is true
that EXO III digests dsDNA from both ends (the original question)? The
answer is yes (3'-5' direction?). Sorry for the fumble, I hope it didn't
ruin your day.
