A simple problem

Well, we know that during DNA replication there is 1 mistake per 10^9 bases per generation. Well lets suppose we have a gene that contains 10^3 bases. In how many generations there will be one mutation? I think in 10^6 generations! Am i correct? :?:

those are probabilities fyi, so it's not 1 mistake per 10^9, it's on average 1 mistake per 10^9.

simply, all those mistakes are then repaired.
Almost 1 mistake per 10,000,000 is taking place while DNA replication according to the book of Brooker ( Principles of Genetics ).

hashem, hashem, you're talking, well, stupid things again...
Definitely not all the mistakes are repeaired (what about evolution?), but the repair systems increase the efficiency by factor of 100 (with Pol's proof-reading of 100 as well)

Cis or trans? That's what matters.
