RAD	20 ± 10	100
rad52	<0.0027	<0.014
rad51	0.14 ± 0.05	0.70
rad54	0.20 ± 0.1	1.0

rad57	0.52 ± 0.2	2.6
rad59	12 ± 7.7	60
rad51 rad59	0.07 ± 0.03	0.35
rad50	11 ± 0.4	55
rad50 rad51	0.47 ± 0.29	2.4
rad50 rad59	3.5 ± 1.6	18
rad50 rad51 rad59	0.34 ± 0.16	1.7
RAD/RAD	17 ± 5.3	100
rad51/rad51	0.17 ± 0.04	1

^aThe frequency of BIR is the number of stable Ura⁺ transformants per microgram with cut DNA divided by the number of transformants per microgram with uncut DNA transformed.
