The absence of pyrimidine dimer excision after UV irradiation in rat cell line was confirmed. The possibility of excision repair system depression by acidification of medium with H3PO4 in HeLa cells has been proved. The results obtained by two different methods of deproteinization and DNA isolation are in good conformity.
Ultraviolet light damages DNA by converting two adjacent thymines into a thymine dimer which is potentially mutagenic, carcinogenic, or lethal to the organism. This damage is repaired by photolyase and the nucleotide excision repair system in E. coli by nucleotide excision repair in humans. The work leading to these results is presented by Aziz Sancar in his Nobel Lecture.
