I just need help with part Bthank you

2) A rare genetic skin disease, known as Xeroderma pigmentosum (XP), presents itself as extreme sensitivity to sun burns, and/or prolonged pigmentation changes. Unfortunately, people who have this disease must avoid as much sun as possible in order to prolong their life. A) Based on the given information on XP, what specific cell component of the skin may be impacted by this disease? Explain your reasoning The specific cell component of the skin that may be impacted is its ability to repair itself. This disease prevents the POL H gene from activating which directly affects skin repair. That is a problem since the squamous part of our skin is highly affected by this disease. B) In a percentage of people who have XP, some do not burn as easily others in the sun, yet they are prone to the development of over pigmentation and more freckled areas. In these individuals what abnormal manifestations do you expect to observe? Explain your answer. Be specific and detailed with your answer.
