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 ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs" within ...

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

Scientists have elucidated the molecular mechanism by which LEM-3 cuts DNA bridges during cytokinesis. If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally ...

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

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

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 ...

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

Chemists induced a cell-like behavior in molecular assemblies called vesicles. They used a sacrificial chemical fuel to make the vesicles divide into smaller versions of themselves. While this process ...

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 ...
