Chromosomal Autoradiography in theiCri du Chat/iSyndrome

摘要

The pattern of DNA synthesis in the chromosomes of Group 4–5 has been analysed in cells from individuals with the cri du chat syndrome. The abnormal chromosome, a No. 5, is one of the pair characterized by relatively early completion of synthesis in the long arms. The two remaining members of this group, characterized by extensive late replication throughout their lengths, therefore may now be recognized as the Nos.
