The genetic material—DNA—of plants and animals (within the latter humans) is stored inside the cell, and DNA packing is guaranteed by proteins called histones. Furthermore, histones play a key role in regulating the activation ...

Cells will ramp up gene expression in response to physical forces alone, a new study finds. Gene activation, the first step of protein production, starts less than one millisecond after a cell is stretched—hundreds of times ...

The genetic material of our cells—DNA—exists in a high-order structure called chromatin. Chromatin consists of DNA wrapped around histone proteins and efficiently packs DNA into a small volume. Moreover, using a spool ...

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" ...

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 ...
