^aTy1his3AI mobility is the average of the number of His⁺ prototrophs divided by the total number of cells plated per culture.

^bThe RAD9/rad9Δ ratio is the Ty1his3AI mobility in the RAD9 derivative of each RTT or rtt strain analyzed divided by the average Ty1his3AI mobility in the rad9Δ derivative of the same strain.

^cThe rttΔ rad9Δ/RTT rad9Δ ratio is the Ty1his3AI mobility in the rad9Δ derivative of each rttΔ strain analyzed divided by 0.604 ×10⁻⁷, which is the Ty1his3AI mobility in the rad9Δ derivative of the wild-type (RTT) strain. NA, not applicable, because the strain did not harbor an rtt mutation.

^drtt control strain with no known effect on genome integrity.

^ertt/genome integrity mutant.
