You tell me. One of the reasons I think life is engineered is because of the interdependency of our DNA and its repair mechanisms.
I've read that each of our cells suffers DNA damage between 10,000 and 1,000,000 time every day. There are various kinds of damage, including oxidation that damages the rungs, broken strands requiring repair, etc. Some of this damage is due to radiation. But other damage is apparently caused by nothing more than friction, as other cellular machinery bounces around against it.
I suppose one could construct an environment free of radiation, free of other molecules bouncing around, and the DNA would hang together as it sat there and did nothing. But could that lesson be applied to the real world?
Our DNA just happens (?) to have encoded within it the transcription specifications for multiple repair mechanisms that fix these kinds of damages. So DNA requires these repair mechanisms, but the manufacture of these repair mechanisms requires that very same DNA.
This is a well-known conundrum. Myself, I think it's an indicator of engineering. Good luck solving it. And if you think you have, then try tackling the other 200 or so functions that every cell must perform, the origin of each facing the same conundrum.
