Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During mitosis, centromeres serve as assembly sites for complex protein ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
July 21, 2021 — During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution ...

A key function of meiosis, then, is to accomplish that reduction to one set of chromosomes. It starts with the pairing of homologous chromosomes: chromosome 19 from mom pairs with chromosome 19 from ...
Study shows that where broken chromosome pieces sit within the nucleus impacts where they reconnect; reveals new guiding principles for cancer genomics BOSTON, Feb. 16, 2012 /PRNewswire-USNewswire/ ...
In the nucleus of eukaryotic cells, DNA is packaged with histone proteins into complexes known as chromatin, which are further compacted into chromosomes during cell division. Abnormalities in the ...
This indicates that the basic chromosome structure had been preserved over 50,000 years in ice, ... And this has only told us about gene activity in skin cells; ...
New findings shed light on how chromosomes manage the various pushing and pulling forces generated when cells divide. Specifically, researchers show that chromosomes resist being punctured by the ...
To study the effect of inhibiting supercoiling on chromosome structure, we performed Hi-C on cells treated with novobiocin, a drug that inhibits DNA gyrase and DNA negative supercoiling.
Research led by the University of Osaka found that calcium ions help maintain the structure of chromosomes during mitosis by promoting their condensation. Increasing concentrations of calcium were ...
