FIG. 3.
Processing of oxidative and spontaneous DNA damage in S. cerevisiae. “X” represents either a base damage which can be recognized and removed by the BER or NER pathway, can be bypassed by TLS, or can block replication causing recombination to occur or an AP site which feeds into any one of the four pathways illustrated. The amount of damage that is processed by each pathway varies depending on the repair background genotype.
