Above - the introduction of the histone H2A.Z increases the mobility of the nucleosome on the DNA and thus encourages gene transcription, i.e. genetic expression. Below - Optical tweezers apply mechanical forces on individual chromatin molecules and form the DNA. As a result, the nucleosome breaks down, and thus it is possible to learn about its stability and mobility.

Researchers at the Faculty of Biology at the Technion have developed a method to break down a single chromatin molecule and study its role in genetic transcription processes
