Cell division allows a single fertilized egg to develop into a living being, our skin to renew itself, and wounds to heal. Before each cell division, termed mitosis, the genetic information must first ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...

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 ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

A prevailing belief that the 3D structure of DNA disappears completely when cells divide has been overturned. Rather than DNA fully unwinding into a flat configuration, some regions of chromosomes ...
