Efficient copying of nonhomologous sequences from ectopic sites via P-element-induced gap repair.


P-element-induced gap repair was used to copy nonhomologous DNA into the Drosophila white locus. We found that nearly 8,000 bp of nonhomologous sequence could be copied from an ectopic template at essentially the same rate as a single-base substitution at the same location. An in vitro-constructed deletion was also copied into white at high frequencies… (More)
