Histone - Wikipedia
Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long. See more

- Histones are proteins that associate with DNA in the nucleus and help condense it into chromatin1234. In eukaryotic cells, chromatin consists of all the DNA within the nucleus and its associated proteins, called histones3. Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones3. Histones provide structural support for a chromosome by wrapping around complexes of DNA, giving the chromosome a more compact shape1.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.A histone is a protein that provides structural support for a chromosome. Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. To do that, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact shape.www.genome.gov/genetics-glossary/histoneHistones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes.www.nature.com/scitable/definition/histones-57/In eukaryotic cells, chromatin consists of all the DNA within the nucleus and its associated proteins, called histones. Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones.www.visiblebody.com/learn/biology/dna-chromoso…In cells, DNA occurs in a densely packed form, with strands of the molecule coiled up in a complicated but efficient space-filling way. A key role in DNA's compactification is played by histones, structural-support proteins around which a part of a DNA molecule can wrap.phys.org/news/2021-06-unraveling-dna-packaging …
