This process is often undergone after exposure to mutagens.
One type of this process was hypothesized by John Tainer to involve a "pinch-push-pull" mechanism. One enzyme involved in another kind of this process is an alkyltransferase that acts on the C-terminal segment of the Ada protein. A third type of this process requires the heterodimer Ku and includes a step performed by the Mre11 complex. Xeroderma pigmentosum results from the inability of skin cells to perform this process after exposure to ultraviolet light. Types of this process include the mismatch and excision types, in addition to the SOS response. This process is often undergone after exposure to mutagens. For 10 points, name this process that puts back together damaged DNA.
