Mitotic recombination events and single-base mutations induced by ultraviolet light in G1-arrested yeast cells

Proceedings of the National Academy of Sciences, Volume 122, Issue 42, October 2025. <br/>SignificanceUltraviolet light (UV) contributes to mutations in all free-living organisms, including humans. We examine two important features of UV-induced mutations in yeast. First, we show that almost all such mutations are a consequence of repair of …
