WebApr 9, 2024 · DNA can be highly compacted. If stretched to its full length, the DNA molecule of the largest human chromosome would be 85mm. Yet during mitosis and meiosis, this DNA molecule is compacted into a chromosome approximately 5µm long. Although this compaction makes it easier to transport DNA within a dividing cell, it also makes DNA … WebStep 1: Crosslinking. Chromatin immunoprecipitation (ChIP) assays begin with covalent stabilization of protein–DNA complexes. Many protein–DNA interactions are transient, and involve multi-protein complexes to orchestrate biological function. In vivo crosslinking covalently stabilizes protein–DNA complexes. In vivo crosslinking is ...
