Scientists studying zebrafish larvae noticed something weird. Skin cells seemed to be dividing without replicating their DNA. They confirmed that what they were seeing was real, upending what we ...

If cells in cell cultures grow while being treated with division-suppressing agents, their growth becomes excessive and they permanently lose their ability to divide. However, if the cells are treated ...

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 ...

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 ...

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 ...

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 ...

Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many ...

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 ...

Our DNA is constantly being packed and unpacked. And there is a good reason for this: depending on its packing state, it performs different functions in the cell nucleus. For most of its life – this ...

Cell division is the process of a cell splitting into two genetically identical daughter cells. The actin protein seen in this video is essential for successful cell division. While actin has several ...
