Telophase

telophase

[′tel·ə‚fāz]
(cell and molecular biology)
The phase of meiosis or mitosis at which the chromosomes, having reached the poles, reorganize into interphase nuclei with the disappearance of the spindle and the reappearance of the nuclear membrane; in many organisms telophase does not occur at the end of the first meiotic division.

Telophase

 

the final stage of cell division. During telophase the movement of chromosomes ceases, the mitotic apparatus disintegrates, and nucleoli appear. A nuclear envelope forms around each of the two groups of daughter chromosomes located at opposite poles of the cell. As the daughter nuclei are reconstituted, division of the cell body—cytotomy, or cytokinesis—occurs, and two cells are formed. The duration of telophase ranges from 1.5 to 400 minutes.

In the present study, the actin cortex layer around the dual contractile ring became thicker between anaphase to telophase compared with that at metaphase, as described by Pielak et al.
However, the analyses of the Nesprin-2 depleted cells revealed the presence of chromatin bridges during ana- and telophase. When we determined the chromatin bridges in cells transfected with SMC control and Ne-2 SMC shRNA at ana- and telophase, we observed that 4.4% (mean value) of control cells harbored chromatin bridges.
Few aberrations were recorded in the interphase, prophase, and telophase. Chromosomal aberrations such as bridges, fragments, binuclei, and micronucleus were observed and recorded (Figure 2).
With respect to the results listed in Table 2, the orange and grape juices of the five food companies, at both exposure times considered, induced significant formation of mitotic spindle changes, represented in this study by colchicine metaphase and anaphase and telophase bridges, proving to be genotoxic, and chromosome breaks, characterized by the formation of micronuclei.

In metaphase, Aurora B is associated to the chromosomes, whereas in anaphase and telophase it is localized to the midzone and midbody, respectively [34].
The late G2 phase, metaphase, and telophase visualizations were obtained from treated zygotes at 21.0, 22.0, and 23.5 hpi, respectively.
The wrinkling revolution process is divided into five stages: (I) prophase stage, (II) prometaphase stage, (III) metaphase stage, (IV) anaphase stage, and (V) telophase stage.
Microtubules formed arrays in the mitotic phase, including a preprophase band (PPB), the spindle apparatus at metaphase and anaphase, and the phragmoplast at telophase, in the CK treatment (Fig.
2013) remains to be established, but the induction of p21 expression certainly contributed to the observed accumulation of cells in telophase.
Oocytes that reached telophase I or metaphase II stages were considered matured.
After telophase, the undamaged chromosomes, as well as the centric fragments, give rise to regular daughter nuclei.
