Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The ...

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 ...

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 ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks” during cell division. Instead of acting like a motor, it works more like ...

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 ...

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 ...

Mitochondrial diseases are severe, often untreatable, and they leave human cells unable to grow normally without outside help. A new study published in Nature Metabolism now shows that a single gene ...
