1974: Nucleosome discovery In the electron microscope, nucleosomes resemble the beads on a string of beads. University of Tennessee/ORNL researchers Ada and Donald Olins discover the nucleosome by electron microscopy and propose its structure. The nucleosome is fundamental to chromosome structure and function as the subunit for packaging DNA within chromosomes and the cell nucleus. The Olins propose that these particles have a dyad axis (like DNA) and pairs of the basic proteins (histones), which is later confirmed. |
