If everything is to run smoothly in living cells, the genetic information must be correct. But unfortunately, errors in the DNA accumulate over time due to mutations. Land plants have developed a peculiar correction mode: they do not directly improve the errors in the genome, but rather elaborately in each individual transcript. Researchers have transplanted this correction machinery from the moss Physcomitrium patens into human cells. Surprisingly, the corrector started working there too, but according to its own rules.
