Feb. 17 If, during the culturing process which forms an essential feature of the preparation of cells for examination of their karyotype, tritiated thymidine (a radioactive precursor of DNA) is added, the resultant metaphase chromosomes become radioactively labeled to a degree that is a function of their recent activity in synthesizing DNA.
