For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Centrosomes serve as the principal microtubule organising centres in animal cells, playing a pivotal role in orchestrating cell division, ensuring accurate chromosome segregation and maintaining ...

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 ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...

David Pellman (left) is a professor at the Dana-Farber Cancer Institute and Harvard Medical School (both MA, USA), who also has affiliations with Howard Hughes Medical Institute (MD, USA) and the ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...
