Recombination products

^aRecombination products from ERCC1⁺ cell lines are the combined results from experiments done here by using the cell line GS21-15 and previously reported results (22). 

^bThis is a subclass of the crossover events obtained from the TK⁻ APRT⁻ selections summarized in A. Of the 72 TK⁻APRT⁻ recombinants derived from ERCC1⁺ cells with a crossover structure, 68 were tested for the accompanying gene conversion of GPT. All 24 TK⁻ APRT⁻ recombinants derived from ERCC1⁻ cells were analyzed for the accompanying gene conversion of GPT.
