dna - How do cockroaches resist the effects of ionizing radiation?


Cockroaches are very hardy insects. It is known that, among other things, they are able to withstand bursts of ionizing radiation that would kill a human being.


The explanations of this observed resistance I've seen include cell division not being that fast in cockroaches, and the relative simplicity of these insects compared to other organisms. I know that microbes are able to resist radiation by having "tough" DNA (more G-C base pairs) and ready repair systems. Do cockroaches also have mechanisms like these, or is it really as simple as them being, well, "simple"?
