Chromosomes continuously develop their shape during cell divisions. Mitotic chromosomes gradually shorten and thicken. Longer ...

QUITE a few physical and chemical inducers of chromosomal aberrations have been tested for interaction of chromatid breaks induced by different agents, the product of interaction being chromatid ...

Here we show that segregation of homologous chromosomes and that of sister chromatids are differentially regulated in Xenopus and possibly in other higher eukaryotes. Upon hormonal stimulation, ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...
