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

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 ...

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 cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...

The awe-inspiring process of cell division can turn a fertilized egg into a baby – or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...

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 ...

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 ...

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 ...

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 ...

Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive virtually every chemical reaction in our cells. For decades, scientists have ...

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 ...
