Molecular biology of chromatin

Last changed: 14 December 2021

Chromatin is the functional form of DNA in a eukaryotic cell nucleus. In chromatin, DNA is packaged together with proteins and RNA. This packaging directly affects all nuclear processes such as gene expression and repair of DNA damage. We study the composition of chromatin, which proteins form or modify it and how chromatin states affect plant development and physiology.
