1) The evolution of a genes and a protein synthesis mechanism followed by correction and repair mechanisms ?
2) The reverse of number 1 ?
False dichotomy. What makes you think that they (#1) didn't evolve simultaneously? What makes you think that they couldn't have evolved simultaneously? What makes you think that they could have evolved separately? Think about this one. It goes back to the cell cycle question that I asked you earlier.
That was a really excellent question (poorly worded, but I fixed it for you). I honestly hope that you do look it up. It is truly fascinating stuff.
I see it as a 'loss of function' mutation that
cripples an existing process. It is Hard to "see how" that is 'building up a genome informationally' as you describe it. I don't see how copying mistakes can be seen as building up genetic information.
