Loss of core histones is now observed in aged cells and may contribute to this phenomenon. Histone loss is coupled to cell division and seems to be triggered by telomeric DNA damage. Figure 2 ...

Each of us has enough DNA to reach from here to the sun and back, more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a ...

We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein structures that are sometimes depicted as discs. Histones carry a slight positive charge ...

The mechanism of a peculiar type of heterochromatin, used by embryonic stem cells to silence 'parasitic' DNA-elements within the context of their highly dynamic pluripotent chromatin. Disclaimer ...

The finding, published Dec. 20 in Plant Cell, was co-authored by Cornell researchers and colleagues from the University of California, Davis, and Shandong Agricultural University in Shandong ...

Cell proteins called linker histones were discovered in the late 1800s. They have been known to influence genetic expression by, for example, providing structure, organization and folding of DNA, but ...
