title: [Reproduction of chicken chromosomes at the end of the DNA synthesis period].
abstract: Reduplication of chicken chromosomes at the end of S-period in the cells of bone marrow was studied, using the method of prolonged labelling with 3H-thymidine and autoradiography. It is shown that during the last hour of the S-period the DNA synthesis in macrochromosomes ends primarily in the centromere region and the regions adjacent to it. Sex chromosomes (ZZ) of cocks accomplish the reproduction simultaneously.
