Yes, it is possible. OK? Can you sleep now?

Cis or trans? That's what matters.

No, i can't. i've got a history test i've got to study for.

Good question.

Theoretical event:
You have one mutated cell. It splits into two.
Then, both of the cells happen to mutate simultaneously so that it is all good again.
Is that possible?

Depends on the mutation. If by during the duplicating of the DNA, the mutation is fixed, then all is good again. There are DNA repair mechanisms in place during DNA replication that this is usually the case. It is only when the mutation is in a place where it is stable enough to proceed thru all the repair mechanisms and is replicated into the next cell's DNA that all is not good. And not necessarily not good for the mutated cell, but for the organism who now has it in its system.
