aDuring interphase, eukaryotic chromosomes are uncondensed and looped, with the ends of the loops attached to the nuclear matrix(see chapter 1) 在相界面, eukaryotic染色体期间是uncondensed和使成环,与圈的末端附有核矩阵(看第1章) [translate] ...
There is no indication that premeiotic centromere associations are involved in prezygotene alignment of homologous chromosomes.doi:10.1007/BF00293189Kathleen ChurchPeter B.

Homologous Chromosomes:Homologous chromosomes are a set of two chromosomes, each of which comes from a different parent (one from the mother and one from the father), but that contain the DNA sequences for the same genes. During meiosis, the homologous chromosomes line up with each o...
Reduction in chromosome number and genetic recombination during meiosis require the prior association of homologous chromosomes, and this has been assumed to be a central event in meiosis. Various studies have suggested, however, that while the reduction division of meiosis is a universally conserved ...
which recycle nucleosomes after the passage of RNAPII at coding regions in the euchromatin48,49.Drosophilaand human Spt6 have been shown to contribute to CENP-A maintenance during interphase33. Thus, we tested whether these factors also contribute to Cnp1 recycling when central core ncRNAs are tr...
6a, b). Together, these results suggest that the global folding patterns of homologous chromosomes are highly similar. Allelic imbalances in gene expression Previous studies of allele-resolved gene expression have identified widespread imbalances in gene expression between different alleles24,25,26,27,...
For three color DNA-FISH, distance was taken if all the probed loci are detected within 1.5μm to avoid taking distance of two loci that are in different homologs, since homologous chromosomes are separated each other before cycle14 embryo. For the FISH in spalt loci, we selected the FISH ...
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, ...
While chromothripsis typically involves multiple focal deletions in a single chromosome (thought to occur during metaphase)20,21, chromoplexy is defined as a series of inter-dependent rearrangements among multiple chromosomes (most likely during interphase)19. Although we did not find evidence of ...
We find that neither nuclear lamina localization nor reduction of Xic homologous pairing influences monoallelic Xist upregulation or choice-making. We also show that transient pairing is associated with biallelic expression, not only at Xist/Tsix but also at other X-linked loci that can escape X...
