In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

Cancer cells with a cell nucleus that is easily deformed are more sensitive to drugs that damage DNA. These are the findings of a new study by researchers at Linköping University in Sweden. The ...

Using advanced microscopy techniques and computational modeling, researchers have discovered how herpesvirus infection affects the host-cell nucleus. Researchers at the University of Jyväskylä ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...
