A chromosome is rarely found in the shape we are used to seeing in biology books, that is to say the typical double rod shape (the X pattern, to put it simply). It is usually "diluted" in the nucleus and creates a bundle that under the microscope appears as a messy tangle. In the last few years such chaos, however, has been "measured" and scientists have unveiled their secret: the genes in the tangle are actually arranged in regions that may perform a functional role. A research coordinated by the scientists at SISSA of Trieste has now developed and studied a numeric model of the chromosome that supports the experimental data and provides a hypothesis on the bundle's function.
