DNA damage leads to a Cyclin A-dependent delay in metaphase-anaphase transition in the Drosophila gastrula. Conclusions: DNA damage delays metaphase-anaphase transition in Drosophila by stabilizing Cyclin A. This delay may normally serve to preserve chromosomal i... TT Su,B Jaklevic - 《Current ...
aSurprisingly, all three were found to be necessary for timely and efficient alignment of the chromosomes during prometaphase. The underlying mechanisms are unknown. 惊奇地,全部三被发现必要的为染色体的实时性和高效率的对准线在prometaphase期间。 部下的机制是未知的。[translate]...
Metaphase IAfter prophase I,the meiotic cell enters metaphase I.During this phase,the nuclear membrane breaks down,allowing microtubules access to the chromosomes.Still joined at their crossover regions in tetrads,the homologous pairs of chromosomes,with one maternal and one paternal chromosome in ...
We find that the sex chromosomes are partitioned to a peripheral spindle domain early in prometaphase I and that their segregation can be accounted for mainly by their reorientation from the parallel to the linear configuration, and little by chromosome-to-pole movement. Further, the behavior of...
Xenopus tropicalis has 10 pairs of homologous chromosomes. How many tetrads in prophase II can be found in the cell of this organism? Xenopus tropicalis has 10 pairs of homologous chromosomes. How many chromatids in Metaphase II can be found in the cell of this organism?
of chromosomes by metaphase is brought about through the loss of some kinetochore-to-pole connections, and the stabilization of others; and (iii) the difference between meiosis and mitosis with respect to chromatid distribution is correlated with a difference in the structure of the kinetochore ...
In hybrid spermatocytes, a high frequency of asynapsis of X and Y chromosomes during the pachytene-like stage and dissociation of these chromosomes during metaphase I (MI) was observed. No autosomal univalency was observed during pachytene-like and MI stages in the hybrids; however, a low ...
during Prophase I and Metaphase I. However, these chromosomes are not arranged in the same way as they were during mitosis. Rather than each chromosome lining up individually across the center of the cell, homologous pairs of chromosomes line up together (formingtetrads, also known asbivalents)...
To answer the question "Chromosomes move towards the pole during," we need to analyze the different stages of cell division, specifically focusing on the movement of chromosomes. 1. Understanding Cell Division Stages: - The cell cycle consists of several stages: interphase, prophase, metaphase, ...
