...physical breaks in the DNA sequence, turning a long string of nucleotides into two shorter strings. In order to survive it is essential that DNA damage is repaired. The “default” repair mechanism simply re-joins the two molecules, but this is an error prone process and small mistakes are often made. So the combination of breaking and repairing DNA can cause small...

...is high but very localised. Heat input to the component is very low with the non-transferred arc process, resulting in very little distortion. Surface finish is good for both processes, although better for the non-transferred arc process.
