Persons with xeroderma pigmentosa lack the ability to repair DNA damage caused by the ultraviolet radiation in sunlight. DNA is subject to damage from the environment. Changes to DNA structure may be copied with the rest of the molecule. Damage may also prevent the DNA from replicating itself. If the damage is major or if it affects nucleotides coding for a crucial part of a protein the function of the protein may be seriously affected or even completely destroyed. Cells contain a number of mechanisms to repair damaged DNA to prevent errors from passed from one generation to the next.
