When no genes are silenced, cell division occurs normally, with each cell giving rise to two. This video was generated within the Mitocheck consortium, whose dataset containing more videos can be ...

When a cell divides, spindle fibers (green) form from centrosomes at each end of the cell and guide the chromosomes (purple), ensuring they are correctly divided between the two new cells. Credit must ...

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 ...

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 ...

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 ...

Understanding the origin of life requires addressing a collection of overlapping scientific questions. We’ve made a lot of progress toward explaining how simple chemicals present on an early Earth ...
