Snip
Any Help Would be Appreciated.
Track down a PolI mutant of E. coli. If my memory serves me right, colE1-based
plasmids require PolI for replication and the ts mutants of PolI (dnaA-?), when raised
to the none-permissive temperature, will "cure" the cell of the plasmid. BTW, all
pBR322 (aka pUC) vectors are derived from colE1-am I right?
Hope this helps.
