Comprehensive and cutting-edge, Digestive System Diseases: Stem Cell WebDec 15, 2005 · The use of direct DNA repeats as homologous recombination substrates provides a measure of both intrachromatid and unequal sister chromatid interactions that can result in two types of products: gene conversion and deletion (Fig. 1; refs. 9, 13 and references therein). Gene conversion associated or not with crossover depends on RAD51.
