  "summary": "During replication, nucleolytic processing of apurinic/apyrimidinic (AP) sites in single-stranded (ss)DNA is attenuated by the evolutionarily conserved 5-hydroxymethylcytosine binding, embryonic-specific (HMCES) protein. HMCES forms a covalent thiazolidine linkage with the ring-opened aldehyde form of a ssDNA AP site to stabilize the AP site and suppress the formation of DNA double-strand breaks.…",
