Changing nutrient environments challenge cells as they affect both protein biosynthesis and cell cycle length. This work ...

It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that ...

The basic building blocks of chromatin are nucleosomes, each of which is composed of 146 bp of DNA wrapped around a histone octamer that consists of two copies each of H2A, H2B, H3 and H4.

Epigenetics regulates gene expression through modifications, impacting health and disease. Aberrant patterns can lead to ...

It is crucial for organisms to be able to control which genes are expressed in which cells and when. Naturally occurring chemical modifications of DNA-binding histone proteins are believed to play an ...

For any organism to survive and thrive, its cells must strictly control which genes are active when and where.

These days, testing your DNA is easier than ever. There are many at-home DNA testing kits to choose from, so all you need are DNA samples to learn more about your heritage and family history.
