Key mechanism in genetic inheritance during cell division identified

...ion of chromosomes during cell division. "In test tube experiments, we've found that the kinetochore proteins form rings around the microtubules and this ring formation promotes microtubule assembly, stabilizes against disassembly, and promotes bundling," says Eva Nogales, a biophysicist who holds joint ...

...y, the Society's peer-reviewed journal. In a test tube study designed to simulate the chemical reactions that occur with the drug when it enters the bloodstream, the researchers showed that methamphetamine reacts with glucose and proteins to form a larger-size "glycated" product.
