When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

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 ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

A research team has identified a new mechanism that controls DNA’s ability to replicate—and thereby a cell’s ability to ...

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

UCSF scientists discover that the spindle, the structure that divides chromosomes equally during mitosis, actually gets stronger when it is stretched.

Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division—a discovery that could lead to new cancer therapies, according to ...

(Nanowerk News) If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell ...

SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters.

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...
