Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...
For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...
Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...
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 starting signal for cell division: Molecular switch ensures that cells divide at the right time
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
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 ...
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 ...
