Abstract
The ionising radiation-sensitive mutants irs 1, irs 2, irs 3, xrs-1 (or xrs-7, EM7 and XR-1 were fused to wild-type cells or to each other in pairs to create hybrid cells. These hybrids were checked chromosomally and their X-ray sensitivity tested. Each mutant was found to be recessive to wild-type and to complement the X-ray sensitivity of the other mutants. Thus there appear to be at least 6 complementation groups for ionising radiation sensitivity in Chinese hamster cells.
