Since 1869, scientists had known about DNA, but its structure remained elusive until 1953. Understanding its shape would help explain how the life-generating molecule worked.

New Twisted 'Knot' Human DNA Structure Discovered—and It Looks Nothing Like the Double Helix Published Apr 23, 2018 at 12:58 PM EDT Updated Apr 23, 2018 at 1:53 PM EDT By Katherine Hignett ...

The central part of each nucleosome (core particle) is a cylindrical structure (5.7 nanometers height and 11 in diameter) formed by approximately two turns of DNA (147 base pairs) wrapped around ...

A new study finds the first Americans had Denisovan DNA, offering clues about ancient immunity and genetic adaptation.

Archaea wrap their DNA (yellow) around proteins called histones (blue), shown above in a 3-D representation. The wrapped structure bears an uncanny resemblance to the eukaryotic nucleosome, a bundle ...
