To solve the question "The homologous chromosomes separate while sister chromatids remain associated at their centromeres in," we need to analyze the stages of meiosis and identify where this specific event occurs.1. Understanding Chrom

2.1 ). In postreplicative (post S phase) cells, chromosomes comprise duplicated sister chromatids. In the cell cycle stage called mitotic metaphase, all sister chromatid pairs are aligned and bi-oriented to the spindle apparatus. In anaphase, all sister chromatids separate in concert and ...
Spiders are renowned for their efficient capture of flying insects using intricate aerial webs. How the spider nervous systems evolved to cope with this specialized hunting strategy and various environmental clues in an aerial space remains unknown. Here we report a brain-cell atlas of >30,000 sin...
in promoter interactivity between differentiation stages (Supplementary Fig.2A–D). These significantly altered promoters are known as Differentially Interacting Promoters (DIPs). Simply plotting DIPs between all six stages of B-cell differentiation, we find that DIPs separate the populations similarly to...
The truncated chromosome 22 that results from the reciprocal translocation t(9;22)(q34;q11) is known as the Philadelphia chromosome (Ph) and is a hallmark of chronic myeloid leukemia (CML). In leukemia cells, Ph not only impairs the physiological signali
In what phase do chromosomes line up in the center of the cell? a. anaphase b. telophase c. prophase d. metaphase Chromosomes and Mitosis: Chromosomes form when a cell enters mitosis. In addition, each stage of mitosis is characterized by change...
First, cells are obtained and cultured in the lab. A chemical is added to arrest cell division at metaphase when chromosomes are maximally condensed. The cells are lysed with a hypotonic solution and the chromosome spread is mounted and fixed on a glass...
Telophase is about the reformation of the nuclear envelope around new nuclei to separate them from each cell’s cytoplasm. Now that the two sets of daughter chromosomes are encased in a new nuclear envelope, they begin to spread out again. When this occurs, it is the end of telophase, and...
To gain further insight into the weak correlation seen in the control cells nuclei (Fig. 1A), we separate the TADs into two major groups: TADs not containing LADs (NonL-TADs) and TADs containing LADs (L-TADs), see Fig. 1B and C. We see essentially no correlation between the ...
