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.

'Anaphase' and cytokinesis in the absence of chromosomes [PDF]
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 role of telomeres at anaphase [PDF]
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.

Sharpening the anaphase switch
Biochemical Society Transactions, 2015The 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 ...

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.

The Plant Anaphase-Promoting Complex/Cyclosome
Annual Review of Cell and Developmental Biology, 2022The anaphase-promoting complex/cyclosome (APC/C) represents a large multisubunit E3-ubiquitin ligase complex that controls the unidirectional progression through the cell cycle by the ubiquitination of specific target proteins, marking them for proteasomal destruction.

Nocodazole pretreatment in anaphase selectively reduces anaphase B in PtK1 cells
Cell Motility, 1983AbstractDuring 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, 1989AbstractAt 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.
