Down's syndrome (DS) is the most common chromosomal abnormality in human. Subjects with DS are known to be peridisposed to develop leukemia. The molecular basis of the association between DS and leukemia is unknown. The unscheduled DNA synthesis (UDS) test measure the ability of DNA-repair in mammalian cells after excision of a stretch of DNA containing the region of damage induced by chemical ...
