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 ...
During cell division, a safety mechanism called the NoCut checkpoint helps delay the final stages of division when DNA bridges are present. The researchers found that this delay allows ESCRT-III ...
Every cell in the human body faces a chronic challenge: protecting its DNA. Whenever cells divide, their genetic material must be copied accurately. But DNA is continuously under attack, and when ...
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 ...
(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 ...
Max Planck Institute of Molecular PhysiologyJul 10 2025 Reviewed 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 ...
Because DNA bridges occur infrequently, the researchers used two approaches to study them. They first analysed large numbers of cells to identify naturally occurring DNA bridges. They also temporarily ...
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 ...
Researchers report that the RNA-processing protein ALYREF binds poly-ADP-ribose at DNA double-strand breaks, delaying repair ...

Trapping cancer-driving DNA rings outside cell nucleus silences their genes, researchers find
Cells from rapidly growing, highly metastatic tumors often contain numerous rings of extrachromosomal DNA (ecDNA). This circular DNA frequently carries oncogenes—genes that promote cancer. Researchers ...
Our DNA is constantly being packed and unpacked. And there is a good reason for this: depending on its packing state, it performs different functions in the cell nucleus. For most of its life – this ...
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as ...
