In E. coli, all newly synthesized DNA appears to be fragmented (an observation that could be interpreted to mean that the leading strand as well as the lagging strand is synthesized discontinuously). However, in E. coli mutants that are defective in uracil-DNA glycosylase, only about half the newly synthesized DNA is fragmented. Explain.
