Despite being densely packed to fit into the nucleus, chromosomes storing our genetic information are always in motion. This allows specific regions to come into contact and thereby activate a gene. A ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

Using computer simulations, chemists have discovered how nuclear bodies called nucleoli interact with chromosomes in the nucleus, and how those interactions help the nucleoli exist as stable droplets ...

What happens when you squeeze DNA? Can pressure reveal something about how our genetic material is packed, protected, and ...

The images show the inside of the cell nucleus at an 8-cell stage (left) and at a later stage (right). Chromosome 19 is shown in red whereas the nucleolus containing the gene-silencing machinery is in ...

Someone has drawn a mascot on the whiteboard in Mitchell Guttman’s molecular-biology laboratory at the California Institute of Technology (Caltech) in Pasadena. It looks like a tangled ball of blue ...

When it comes to DNA, one pesky mosquito turns out to be a rebel among species. Researchers at Rice University's Center for Theoretical Biological Physics (CTBP) are among the pioneers of a new ...
