'Anaphase' and cytokinesis in the absence of chromosomes

Nature, 1996
Anaphase and cytokinesis are key processes in the segregation of replicated chromosomes to the daughter cells: in anaphase, chromosomes move apart; in cytokinesis, a cleavage furrow forms midway between the separated chromosomes. Some evidence suggests that chromosomes may be involved both in controlling the timing of anaphase onset and in dictating ...

The mechanism of anaphase spindle elongation

BioEssays, 1989
AbstractAt anaphase chromosomes move to the spindle poles (anaphase A) and the spindle poles move apart (anaphase B). In vitro studies using isolated diatom spindles demonstrate that the primary mechano‐chemical event responsible for spindle elongation is the sliding apart of half‐spindle microtubules.

Nucleotide requirements for anaphase chromosome movements in permeabilized mitotic cells: Anaphase B but not anaphase a requires ATP

Cell, 1982
Permeabilized PtK1 cells continue to undergo anaphase chromosome movements provided MgATP is included in the lysis medium. However, chromosome-to-pole movement (anaphase A) and spindle elongation (anaphase B) differ with respect to nucleotide requirements.

Chromosome errors at mitotic anaphase

Genome, 1992
Errors in mitotic divisions were assayed using various satellite DNAs as probes, hybridized in situ, to show that they included nondisjunction, chromosome and chromatid lagging, chromatid malsegregation, and monopolar segregations. The total rates of error were 1.7, 1.1, and 0.6% for chromosomes X, 17, and 18, respectively. Lagging was the most common

Rephrasing anaphase: separase FEARs shugoshin

Chromosoma, 2005
Cleavage of the ring-like cohesin complex by separase triggers segregation of sister chromatids in anaphase. This simplistic model has recently been extended by exciting discoveries on three levels: regulation of anaphase by posttranslational modifications and the cohesin protector shugoshin; non-proteolytic roles of separase; and cohesin-independent ...

Enzymology of the Anaphase‐Promoting Complex

2005
The anaphase-promoting complex (APC) is an ubiquitin-protein ligase that promotes mitotic progression by catalyzing the ubiquitination of numerous proteins, including securin and cyclin. Its complex subunit composition and extensive regulation make the APC an active subject of investigation for both cell biologists and enzymologists.

The role of telomeres at anaphase

Chromosoma, 1962
1. Chromosomes ofAllium cepa, Tradescantia virginiana andT. paludosa were studied at mitosis in order to investigate the behavior of telomeres at anaphase. The studies were made in untreated fixed material, in cochicine treated cells, and in living staminal hairs. 2. InAllium cepa andT.

The anaphase promoting complex.

Cancer surveys, 1997
We have proposed a preliminary model of how the anaphase promoting complex functions throughout the cell cycle, but despite the flurry of recent publications characterizing the APC--its components, regulation and substrate specificity--many fundamental questions remain to be answered.
