Fillling in/Chewing back/Blunting - will this work?

[Andy Groves]

A simple question for you. Will this reaction work?


BamHI end:      G A T C C N N N N N N .....
                        G N N N N N N ......



Add Klenow and A, T, G, but *not* C



to give           A T C C N N N N N N .......
                  T A G G N N N N N N ........


....i.e., filling in three bases and chewing back the lone G to give a
blunt end.



Half my molecular colleagues say this will work, the other half say I will
be left with a protruding G.......



Any advice appreciated!
