Structural analyses using cryogenic electron microscopy reveal how the versatile oncoprotein DEK binds nucleosomes, bends linker DNA, and coordinates histone modifications to regulate gene expression.

As a cell divides, its DNA -the genetic material- is duplicated and condensed into structures called chromosomes, which are carefully organized and distributed so that each daughter cell acquires a ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Researchers identified OMC1, an oocyte-specific protein that maintains chromosome cohesion throughout reproductive life, and ...
