As we grow older, our bodies accumulate "zombie cells"—living cells that have stopped dividing or functioning normally but ...

In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA ...

Cell division is a complex process. At the heart of this complexity is a membraneless organelle called the centrosome, which ...

A previously unknown protein, hidden in RNA thought not to encode proteins, helps cells divide correctly. The RNA molecule ...

Modern technologies have made it possible to uncover a growing "hidden proteome"—proteins encoded by parts of the genome that ...

During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers—complex machinery ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

Trying to hit a target size before dividing seems like the best strategy for maintaining a precise cell size, but bacteria don't do that. Now we know why. When a single bacterial cell divides into two ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, a group now ...

When we talk about memories in biology, we tend to focus on the brain and the storage of information in neurons. But there are lots of other memories that persist within our cells. Cells remember ...

Researchers at the Francis Crick Institute, King's College London and Complutense University of Madrid have shown that γδ T ...

It is one of the wonders of nature: multiplying cells are able to precisely copy their genetic material, once and only once, and spatially segregate the resulting two sets of chromosomes when the time ...
