Analysis of the DNA replication pattern of a translocation (tX/X, qter----p221::p223----qter) chromosome in leukocyte and fibroblast cultures.
The results of a detailed analysis of DNA replication in a late replicating tX/X chromosome (qter----p221::p223----qter) are reported. The chronology of DNA replication has been analyzed by comparing (a) the replication patterns of each of the two moieties of the translocation chromosome in different cells and (b) the two moieties with each other in the same cell. The study has been done on leukocyte and fibroblast cultures after BUdR incorporation. A comparison with the late replication pattern of the normal X chromosome has also been done.
