to throw light on the nature of that increased capacity to tolerate unexicsed dimers we have compared restoration of dna daughter chains in cells of the uvr+ and uvr- genotype and found that integrity of uvr loci is a conditio sine qua non for an effective restoration of daughter chains , but that depression of excision activity by the mentioned pretreatment does not influence restoration of dna daughter chains .
