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.

1; TI, TelophaseI; MII, MetaphaseII; SEM, standard error of the mean.
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
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).
