Scientists accidentally discover DNA that breaks the rules of life

A Pond Protist Just Rewrote One of Biology’s ‘Universal’ Rules

Researchers testing a single-cell DNA sequencing pipeline unexpectedly found a freshwater protist that appears to reinterpret two genetic stop codons, adding a new exception to one of biology’s foundational rules.

Key Takeaways

Researchers testing a single-cell sequencing pipeline found a protist with an unusual genetic code.
The organism appears to reassign two codons normally used as stop signals.
