anaphase

[′an·ə‚fāz]
(cell and molecular biology)
The stage in mitosis and in the second meiotic division when the centromere splits and the chromatids separate and move to opposite poles.
The stage of the first meiotic division when the two halves of a bivalent chromosome separate and move to opposite poles.

Expression of Centromeric Sequences Induces Mis-Segregation in Anaphase. The human (HUES-10, HT1080) and murine (E14TG2A) cells were transfected with the respective satellite expression constructs outlined above and the insert-less pIneo2 vector in a parallel control experiment.
Kazic and Sofradzija (1985) studying the effects of Largaktil, a Nozinan and Valoron came to the conclusion that Nozinan significantly reduced mitotic activity and causes major changes in interphasic nuclei and the occurrence of abnormal metaphase and anaphase. Largaktil at the start of treatment, manifest a stimulative effects, but also the appearance of nonspecific metaphases, while very strong mutagenic effects of Valoron is manifested through inhibition of mitotic activity, the occurrence of abnormal prophase, metaphase and anaphase, and changes in the structure of chromosomes.
The chromosomes in precocious migration in metaphases I may have originated from univalents in diakinesis or have been a result of precocious terminalization of chiasma and the late terminalization of these chiasmas makes the laggard chromosomes in anaphase I (SOUZA-KANESHIMA et al., 2010).

It induced multipolar anaphases and telophases and chromosome lagging.
lyoni, with n = 11 or n = 12 = 11 + X, confirmed the regular reductional segregation of all the chromosomes in the preceding anaphase I and the meta- and submetacentric morphology of the chromosomes (Figs.
The predominant abnormalities consisted of chromosomes/ nuclei in stickiness, bridges at anaphase and telophase, C-metaphases, unoriented chromosomes at metaphases, and chromosomes/chromatids or even lost fragments at anaphases (Table 4 and 5, Figure 4).
