RPA bound to ssDNA directs the nuclease cleavage of adjacent dsDNA by the MRX–Sae2 complex. (A) Representative nuclease assays showing the degradation of 3′ tailed (PC216 and PC216_C_50 nt), 5′ tailed (oligonucleotides PC216_50 nt and PC217), and blunt-ended DNA (PC216 and PC217) by MRX–Sae2 without or with RPA. The red asterisk indicates the location of the 32P label. (B) Representative nuclease assays as in A showing the degradation of tailed (oligonucleotides PC204 and PC217) and blunt-ended (PC216 and PC217) DNA by MRX–Sae2 with or without RPA.
