[Distribution of chromosome breakage point induced by arabinosylcytosine on in-vitro human lymphocytes].
The cytogenetic effects of arabinosyl cytosine on human leukocytes in vitro has been studied using continuous and discontinuous treatments. Optimum activity occurs at the end of the S period. Interchromosomal distribution of breaks is non-random. The hypothesis of a very late replication for some chromatid segments is discussed. The relations between banding and the position of breaks are discussed.
