Exposure to mutagens, or mutation-causing agents, can not only bring about changes in DNA but also appear to induce errors when genes are transcribed to make proteins, which may be an important factor in age-related diseases.

The error-free division of mouse oocytes—the precursors of eggs—needs kinetochores that are rich in a specific microtubule crosslinker, RIKEN researchers have discovered. This finding could explain why the division of ...
