5'- 3'

[Lauri Lintott]

I need to chew up a piece of DNA 5' to 3' in a buffer that is pH
7.5.  I thought maybe I could use DNA pol 1.  I assume that if I
don't add any nucleotides the 5' to 3' exonuclease activity of
this enzyme should be favored.  Does this sound right to any one?
Has any one tried it?
Thanks in advance.
