NORAD-induced Pumilio phase separation is required for genome stability The noncoding RNANORADmaintains genome stability in mammalian cells by sequestering Pumilio proteins in phase-separated compartments. Mahmoud M. Elguindy &Joshua T. Mendell
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell? How many chromosomes are visible at the beginning of mitosis? When during the cell cycle are chromosomes visible? In which phase of mitosis do chromosomes line up at the middle of the cell?
Chromosomes may exist as either duplicated or unduplicated—unduplicated chromosomes are single linear strands, whereas duplicated chromosomes (copied during synthesis phase) contain two copies joined by a centromere. Compaction of the duplicated chromosomes during mitosis and meiosis results in the classic ...
virginiana suggest that it, like many species in North America, may have been separated into two vicarious groups as the result of uplifting of the Rocky Mountains (Staudt, 1999). Using morphological and RAPD data, Harrison et al. (1997) concluded that F. virginiana subsp. platypetala was ...
sex chromosomesandautosomes. Autosomes control theinheritanceof all the characteristics except the sex-linked ones, which are controlled by the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes. All act in the same way during cell division. For information on sex...
which enabled the illumination of a thin area within a single cell while reducing the background noise (green line in Fig.1e45,57,66). Clear, well-separated dots were detected (Fig.1f) with a single-step photobleaching profile (Supplementary Fig.1c), suggesting that each dot represents a ...
separated and equally distributed to the daughter cells.You may recall that during the S phase each chromosome is duplicated, forming a new chromosome with two sister chromatids, which become visible microscopically early in the M phase.You may recall that during the S phase each chromosome is ...

Chromosome architecture and low cohesion bias acrocentric chromosomes towards aneuploidy during mammalian meiosis Bellou et al. show that acrocentric chromosomes, such as chromosome 21, are more prone to aneuploidy in oocytes due to their unique architecture and lower cohesion levels, which lead to ineff...
When we could not determine whether the sex chromosome axes were synapsed or separated, those pairs were judged as indeterminate. Notably, we were unable to distinguish using this method whether synapsis involved stable homologous pairing at PARs or nonhomologous association at chromosomal locations ...
