DNA is very long\u2014for humans, the molecule is estimated to be about 2 m in length. 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&#8217;s compactification is played by histones, structural-support proteins around which a part of a DNA molecule can wrap. The DNA-histone wrapping process is reversible\u2014the two molecules can unwrap and rewrap\u2014but little is known about the mechanisms at play. Now, by applying high-speed atomic-force microscopy (HS-AFM), Richard Wong and colleagues from Kanazawa University (NanoLSI WPI) provide valuable insights into the spatiotemporal dynamics of DNA-histone interactions.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-06-unraveling-dna-packaging-histones-interact.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Unraveling DNA packaging: How histones and DNA interact<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The genetic material of most organisms is carried by DNA, a complex organic molecule.
