Witryna29 lis 2024 · The packaging of DNA into the chromatin presents a barrier to all DNA-based processes. Due to the high dynamic arrangement of proteins and DNA, chromatin can readily change its shape and structure. Chromatin relaxation occurs rapidly at the site of a DNA damage, which allows the repair proteins to bind to DNA and repair it. ... WitrynaDuring the initial stages of DNA packaging, the DNA is reduced to an 11 nm fiber that denotes approximately 5-6 folds of compaction. This is achieved through a nucleosome order of packaging.
