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 ...

DNA, though tightly packed in the nucleus, is constantly threatened by damage from metabolism and external stressors. One particularly severe form of DNA damage is the so-called DNA–protein crosslinks ...

A time-delay circuit enables precise control over the division of synthetic DNA droplets, which mimic biological Liquid-Liquid Phase Separation (LLPS) droplets found in cells. By utilizing a ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

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

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 ...

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 division, and the ...

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

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 ...

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