Abstract

When exponential-phase cultures of Deinococcus radiodurans are exposed to a 5000-Gray dose of gamma radiation, individual cells suffer massive DNA damage. Despite this insult to their genetic integrity, these cells survive without loss of viability or evidence of mutation, repairing the damage by as-yet-poorly-understood mechanisms.
