Oxford Pond Protist Rewrites Genetic Stop Signals, Challenging Evolutionary Assumptions
A previously unknown ciliate protist, Oligohymenophorea sp. PL0344, discovered in an Oxford pond, uses two standard genetic stop codons to encode different amino acids, defying long-held evolutionary rules. The accidental finding, published in 2023, has led to the identification of similar genetic variations in marine ciliates, highlighting the flexibility of the genetic code in microscopic life.
