When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

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 ...

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 ...

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 ...

Researchers have revealed a surprising new role for a key protein in cell division. The discovery, reported in two back-to-back papers, challenges long-standing models and textbook accounts in biology ...

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 ...

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 ...

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 ...
