Plant derived DNA can be absorbed thru ingestion directly into the bloodstream, without being broken down. GMO camp going to have a difficult time with this one, as it was a 1k person study

In one of the blood samples the relative concentration of plant DNA is higher than the human

edit to add another study on blood disorders

"[O]ur study demonstrated that Bt spore-crystals genetically modified to express individually Cry1Aa, Cry1Ab, Cry1Ac or Cry2A induced hematotoxicity, particularly to the erythroid lineage," wrote the authors. "This finding corroborates literature that demonstrated that alkali-solubilized Bt spore-crystals caused in vitro hemolysis in cell lines of rat, mouse, sheep, horse, and human erythrocytes and suggested that the plasma membrane of susceptible cells (erythrocytes, in this case) may be the primary target for these toxins."
