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 ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

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 ...

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a ...

Timelapse of a gene-edited medaka fish embryo undergoing mitosis. The mitotic spindle – the green strands in the middle of the cells – can be seen aligning and segregating duplicated chromosomes, ...

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 ...

Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...

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 ...

Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the ...
