We could just use statistics.

Example: the DNA has 3.2*10^9 base pairs. We have trillions of cells. Even if each cell division introduced 1000 mutations, the cells would hit the Hayflick Limit at around 60 divisions. The last generation of a cell line would have 60000 mutations on average and the other cells less so.

It's nothing compared to the size of the DNA. I can't go through with the calculation right now but my guess is that it wouldn't take more than a billion cells to get to your birth DNA.

That part of my argument was just an easy way to deal with the writer's assumptions.

Also - we likely could correct most of the damage by sequencing only one or a few cells. Almost all human genetic variation is in a relatively small number of well known locations in the genome - if we assume mutations occur at random locations, we can fix almost all of them by looking at any reference genome.

If something is missing replace with frog DNA. Should not cause any problems.

Cool, I've always wanted to procreate without the pesky inconvenience of sex... ;)
