Research ProjectThe purpose of my work was to irradiate DNA samples with UVA light in the presence of different substances to study the possible mechanisms involved in the induction of DNA lesions by these wavelengths. The determination and quantification of different types of DNA lesions formed after irradiation was performed using enzymes for DNA repair that recognize and cleave the site containing specific lesions. Complementing these analyses, immunological and chromatographic tests were performed. With the implementation of these analyses, we sought to uncover how the damages induced by UVA light in the DNA molecule are generated by examining the indirect (reactive species) and direct (photon absorption by the DNA molecule) mechanisms. |
