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 ...

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 ...

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 ...

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 ...

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 of protein fibers around ...

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 ...

Just one enzyme manages the refilling of the cellular soda machine that replicates our genes. PLK-1 initiates a process in two protein groups, leading to creation of new CENP-A proteins. These CENP-A ...

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