A two-cell embryo of , stained to visualize DNA (red) and the cell membrane (green). One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can ...

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 ...

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 ...

New findings shed light on how chromosomes manage the various pushing and pulling forces generated when cells divide. Specifically, researchers show that chromosomes resist being punctured by the ...

Researchers discover that a specialized part of the chromosomes, essential for a correct cell division, is smaller and weaker in stem cells, when compared to the ones of differentiated cells. The ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within ...

Some cells can turn cancerous when they divide, due to chromosomes getting “lost” in the process. In a new study, researchers at the University of Warwick have uncovered what happens to these lost ...

Our genetic code is stored in chromosomes that are composed of DNA (deoxyribonucleic acid). To make sure the genetic code is maintained accurately in all the cells, our cells must replicate precisely ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, ...
