31. The diagram shows a cell nucleus in prophase of mitosis.8 Which statement describes the chromosomes found in each daughter nucleus immediately following cell division of this cell by mitosis? B A 8 chromosomes, each consisting of 2 molecules of DNA B 8 chromosomes, each consisting of 1 mo...
During which phase of the cell cycle does DNA replication occur? a. Prophase b. Interphase c. Cytokinesis d. G1 phase Cell Cycle: The cell cycle is the phase in which a cell goes through during its lifespan. The cell cycle is composed ...
This gene is a member of the SCC3 family and is expressed in the nucleus. It encodes a component of cohesin, a multisubunit protein complex that provides sister chromatid cohesion along the length of a chromosome from DNA replication through prophase and prometaphase, after which it is dissocia...
Aurora A plays a role in cell cycle regulation during anaphase and/or telophase, in relation to the function of the centrosome/spindle pole region during chromosome segregation. Aurora A plays a key role during tumor development and progression and is overexpressed in many human cancers including ...
Understanding the role of sex chromosomes in germ cell differentiation and functions would shed light on the evolution of sex chromosomes and meiotic mechanisms, which are unique to the germ cells. In Mus musculus, the deletion of the Y chromosome region harboring Sry results in sex reversal (XY...
we detected different clusters of spermatogonia, spermatocytes during pachytene and spermatocytes during metaphase I, and large clusters of spermatids. The morphology of their nuclei discriminated different cell types after DAPI staining according to the previously published results forCobitisspecies17,24,48...
Mitosis in onion cells of the root meristem. In the central rowof cells there is a prophase cell showing chromosomes. Below a typical anaphase can be seen. Light microscope micrograph.,站酷海洛,一站式正版视觉内容平台,站酷旗下品牌.授权内容包含正版商业图
As there have been four reported chromosomal rearrangements1–4, suggesting the presence of a potential KS gene in the overlapping region of 12q24, we obtained the available lymphoblastoid cell lines from Patient 1, who carries a de novo apparently balanced translocation t(7;12)(q22;q24)1...
Cell wallMicrotubulePreprophase band?In some plant tissue types, new cross-walls tend to divide parental cells equally and to meet parental walls at right angles while tending to have minimal surface area. A previously proposed model that I call the reach model suggests that this feature origin...
Cell death is not the result of an aberrant DNA damage response but is triggered by centrosome-based mitotic errors. In addition, Cep63 loss severely impairs meiotic recombination, leading to profound male infertility. Cep63-deficient spermatocytes display numerical and structural centrosome aberrations,...
