Chromatid lesions and chromatid core morphology
Cytogenetic and Genome Research, 1981A silver-staining technique revealed the core morphology of metaphase chromosomes of irradiated CHO cells with chromatid lesions (breaks, gaps). These cells were photographed before and after silver staining. As a rule, the core was not continuous in chromatid gaps, suggesting that the chromatid is broken in many so-called gaps. Ten cytogeneticists who

AbstractSister chromatid exchange (SCE) refers to the interchange of DNA between replication products. The technique for detecting such exchanges takes advantage of the semiconservative nature of DNA synthesis. 5′‐bromodeoxyuridine (BrdU) is incorporated into the newly synthesized DNA.

Sister chromatid exchanges (SCEs) represent the interchange of DNA replication products at apparently homologous loci. These exchanges presumably involve DNA breakage and reunion, although little is known about the molecular basis of sister chromatid exchange formation, and information about the biological significance of exchanges is largely ...

Trends in Biochemical Sciences, 1999
Loss of cohesion between sister chromatids triggers their segregation during anaphase. Recent work has identified both a cohesin complex that holds sisters together and a sister-separating protein, separin, that destroys cohesion. Separins are bound by inhibitory proteins whose proteolysis at the metaphase-anaphase transition is mediated by the ...

Medical Hypotheses, 1999
The paper studies mammalian chromatids conformed as donut-like rings. Albeit enacting many topologic and dynamic aspects of straight chromatids (e.g. replication, eversion, antipodal segregation at anaphase, etc.), rings differ in certain properties regarding in particular disposal of soliton-like, kinked frustrations of their chirality during ...
