Scientists find stop-codon reassignment
- Researchers discovered DNA in a microscopic pond organism where genetic “stop signals” have been reassigned, meaning its code reads stops differently. (x.com) - The paper reports natural reassignment of stop codons—normally used to end protein synthesis—showing the genetic code isn’t universally fixed across life. (x.com) - That molecular flexibility challenges assumptions about protein translation and could influence synthetic biology and evolutionary studies. (x.com)
