Figure 5. Residual NHEJ in the chromosomal suicide deletion assay with catalytically defective Dnl4.

(A) Diagram of the suicide deletion chromosomal assay used to determine NHEJ efficiency in panels (B) to (D). (B) Cells were pre-grown to stationary phase in synthetic defined medium prior to plating to galactose. When indicated, the chromosomal dnl4 allele was complemented with a plasmid bearing wild-type DNL4 (pDNL4). (C) Cells were pre-grown to log phase in YPA-Glycerol. (D) Epistasis analysis of Dnl4 catalytic mutants with nej1Δ. Results are the mean ± standard deviation of at least three independent experiments.
