1st, as the subject alludes, I don't know what the command is to delete a character in EMAC (the default editor that appears when one uses rn.
Anyway, my question is regarding DNA repair enymes that prevent uncontrolled growth of a cell by changing the bases to the original base. How could these
enzymes have evolved? Wouldn't the cell that has mutated to have uncontroled
growth be selected for? I can't think of a scenrio where these repair enzymes
could be selected for.
