Two representations show chromosomes 17 and 18 as simulated by scientists at Rice University investigating the mechanisms behind coherent movement in the nucleus of a cell during interphase. At left, the images in the left column show blue and red beads separating by type, while the right column shows orange and cyan chromosomes separated by chain. The vector field representation on the right shows the magnitude and direction of the displacement of chromosomal units over a time scale of 10 seconds. It highlights the discovery that distinct chromosome regions display coherent motion. (Credit: Center for Theoretical Biological Physics/Rice University)
