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.
To determine if aurora A kinase (AAK) plays a post-metaphase role in Drosophila S2 cell division, AAK was knocked down by RNA interference (RNAi), and microtubule (MT) intensity in the spindle midzone during late anaphase was quantified (Fig.

The damaged chromosomes, in the form of acentric chromatids or chromosome fragments, lag behind in anaphase when centric elements move towards the spindle poles.
Several chromosomal aberrations (CA's) like chromosomal break, stickiness, laggard, and multipolar anaphase have been formed.
It delivers the two groups of chromosomes to positions adjacent to the polar furrows midway between pairs of plastids in anaphase and a phragmoplast is constructed in the midzone (Fig.
10 and 50 [micro]g/ml number of prophases and telophases generally increases by prolonging treatments, and the number of metaphases and anaphases decreases.
This can be seen from the simulation results in To improve the searching ability, especially at the anaphase, a hybrid MPPSO with sub swarms, called HMPPSO, is developed.
RHAMM is a centrosomal protein that localizes to interphase microtubules, spindle poles, the anaphase midbody and the telophase midzone microtubules.
The main reason for this conceptual difficulty, in our experience, is the complexity of the forward and reverse movements involved: equator-ward migration from prophase to metaphase, and then pole-ward migration from metaphase to anaphase.
In order to investigate for the occurrence of persistent nucleolus phenomenon in metaphase and anaphase cells, ten slides were considered for each variety and all metaphase and anaphase cells were analyzed.
These manifestations include anaphase bridges that may be caused by double-strand DNA breaks, as well as lagging chromosomal material (20).
