Abstract excerpt
We wanted to establish whether strand breaks and gaps, arising during the removal of uracil from newly-synthesized DNA, can be utilized as strand discrimination signals by the methyl-directed mismatch repair system of Escherichia coli. For this purpose, we constructed a series of M13 heteroduplexes that contained a single uracil residue situated either upstream or downstream from a G/T or an A/C mispair....
