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 ...
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 ...
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 ...
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 ...

A DNA typewriter recorded a mouse embryo’s family tree from its first two cells
A mouse embryo has now been made to write its own family tree. A recording device called the DNA Typewriter, built in Jay Shendure’s laboratory at the University of Washington, kept a running log of ...
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 ...
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 ...
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 ...
Scientists have traced the development of a mouse embryo from its first two cells to the formation of organs, using a ...
Learn how DNA can be exchanged between two cells that connect by forming nanotubes, and find out why this is crucial for cancer research. When cells in our body are going through a rough patch due to ...

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 ...
