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 ...

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

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

Viruses are known to use the genetic machinery of the human cells they invade to make copies of themselves. As part of the process, viruses leave behind remnants throughout the genetic material ...

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 ...

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

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

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

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

Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...
