Problem:

Question: How long do melanocytes and melanosomes continue to protect DNA after UV exposure?

Question: If skin is tanned, then over the next month it is shed, will melanocytes continue to produce high levels of melanin to keep the new skin tanned without requiring more UV exposure?

Question: The cells react by producing more melanin after exposure but will they continue to do this in new skin cells?

Please provide detailed answer of all the questions.
