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.
9) Total of evaluated Degenerated oocytes oocytes n (%) 172 3 (174) Telol: Telophase
Further examination of the microtubule arrays at telophase
showed that the microtubules were arranged at the equatorial plate in the CK and B treatments (Fig.
Damage of oocytes quality during warmer periods, leading to meiotic arrest of oocytes at anaphase and telophase
stages, could be provoked by several factors.
Nuclear maturation rate in Table VI represented by the percentage of oocytes reaching telophase
I (TI) and metaphase II stages (MII) was higher (p less than 0.
10 and 50 [micro]g/ml number of prophases and telophases
generally increases by prolonging treatments, and the number of metaphases and anaphases decreases.
The sequence of events is as follows: primary phragmoplasts develop in the interzones between pairs of telophase
II nuclei, secondary phragmoplasts develop adventitiously among all non-sister nuclei and all six phragmoplasts merge.
Irregular chromosome segregation, characterized by precocious chromosome migration to the poles at metaphases (Figure 1b and f), laggard chromosomes at anaphases (Figure 1c and g), leading to micronuclei formation at telophases
(1c, d, e, and h) and tetrads (Figure 1i) were recorded in all the hybrids and their genitors in different amounts.
enucleation: an improved method to prepare recipient cytoplasts for use in bovine nuclear transfer.
Survivin is a chromosomal passenger protein involved in metaphase, anaphase and telophase
, the fragments or whole chromosomes give rise to one or several secondary nuclei which are small than the main daughter nucleus and are therefore called micronuclei (Schmid, 1975; Heddle et.
The cells were recorded as normal or aberrant in the different stages of the cell cycle namely: interphase, prophase, metaphase, anaphase or telophase
