A study undertaken by an international team led by Ludwig-Maximilians-Universitaet (LMU) in Munich molecular biologist Axel Imhof sheds new light on the mechanisms that control the establishment of epigenetic modifications ...

New roles for DNA-packaging proteins

How can human cells pack 3-meter-long DNA into their tiny nuclei and unpack it only where and when it is needed? This fascinating process is far from being completely understood.

How our single-celled relatives package their DNA

A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman ...

Recipe for making a fruitfly

Researchers have used mass spectroscopy to determine the absolute copy numbers of nuclear proteins and histone modifications in the Drosophila embryo. The results provide new insights into the mechanisms of animal development.
