Unlike mice, humans are diurnal and hence one can expect the opposite results in humans greater ability to repair DNA damage caused by UV radiation in the morning.Dr. Sancar was awarded the Nobel Prize for mapping nucleotide excision repair the mechanism that cells use to repair UV damage to DNA. According to a Nobel Prize release, people born with defects in this repair system will develop skin cancer if they are exposed to sunlight. The cell also utilises nucleotide excision repair to correct defects caused by mutagenic substances, among other things.Unlike mice, humans are diurnal and hence one can expect the opposite results in humans greater ability to repair DNA damage caused by UV radiation in the morning.Dr. Sancar was awarded the Nobel Prize for mapping nucleotide excision repair the mechanism that cells use to repair UV damage to DNA.
