Investigating chromatin's 3D architecture reveals its influence on gene regulation, shedding light on mechanisms underlying ...

Cramming meters-long DNA strands into a cell’s tiny nucleus is an astonishing feat. A new study suggests that cells from plants (shown), animals and fungi accomplish it one of two ways.

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these ...

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 ...

In the cell nucleus, DNA wraps around what are called histone proteins, forming regularly spaced spherical bodies called nucleosomes. Thus, large portions of the genetic material are inaccessible ...

In diagrams and illustrations of cells, DNA is sometimes shown as a mass in the cell's nucleus, like a bowl of ramen noodles. For many years, it's been standard practice to take images of ...

The process of DNA packaging in cell nucleus revealed. Lomonosov Moscow State University. Journal Current Biology DOI 10.1016/j.cub.2016.07.020. Keywords ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

In cells with different functions, specific parts of the DNA change their packaging and spatial organization within the nucleus. This results in different genes being turned “off” and “on”.
