Anaphase A

Seminars in Cell & Developmental Biology, 2021
Anaphase A is the motion of recently separated chromosomes to the spindle pole they face. It is accompanied by the shortening of kinetochore-attached microtubules. The requisite tubulin depolymerization may occur at kinetochores, at poles, or both, depending on the species and/or the time in mitosis.

Sharpening the anaphase switch

Biochemical Society Transactions, 2015
The segregation of sister chromatids during mitosis is one of the most easily visualized, yet most remarkable, events during the life cycle of a cell. The accuracy of this process is essential to maintain ploidy during cell duplication. Over the past 20 years, substantial progress has been made in identifying components of both the kinetochore and the ...

The many phases of anaphase

Trends in Biochemical Sciences, 2005
Anaphase is the stage of the cell cycle in which duplicated chromosomes separate and move towards opposite poles of the cell. Although its chromosome movements have always been viewed as majestic, until recently anaphase lacked obvious landmarks of regulation.

Nocodazole pretreatment in anaphase selectively reduces anaphase B in PtK1 cells

Cell Motility, 1983
AbstractDuring early anaphase PtK1 cells were briefly treated with the rapidly reversible microtubule (MT) poison nocodazole. This treatment abruptly stopped chromosome motion and effected a large decrease in spindle birefringence. On removal of the drug, chromosome to pole motion (anaphase A) returned, though at a lesser rate but not extent than ...

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.

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

Anaphase Inactivation of the Spindle Checkpoint

Science, 2006
The spindle checkpoint delays cell cycle progression until microtubules attach each pair of sister chromosomes to opposite poles of the mitotic spindle. Following sister chromatid separation, however, the checkpoint ignores chromosomes whose kinetochores are attached to only one spindle pole, a state that activates the checkpoint prior to metaphase. We

'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 ...

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.
