question: What are the roles of LEM-3?
answer: LEM-3 is a midbody-tethered DNA nuclease that resolves chromatin bridges during late mitosis. The conserved LEM-3/Ankle1 nuclease is involved in the combinatorial regulation of meiotic recombination repair and chromosome segregation in Caenorhabditis elegans. LEM-3 is able to process erroneous recombination intermediates that persist into the second meiotic division.
