I2: The final step in "base editing" requires the cell's normal DNA repair machinery to correct the pairing shown above. Given your knowledge of DNA repair, name the repair pathway that would act on the DNA molecule above, and describe all of the steps and proteins involved in this repair pathway. (Hint: Since DNA replication has already been completed in this case, "proofreading" is not the correct answer.)

Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
