Protozoans Found With No Dedicated Stop Codons
Karen Zusi | Oct 1, 2016
Some ciliates use the same trio of nucleotides to code for an amino acid and to stop translation.
Ciliates Are Genetic-Code Deviants
Karen Zusi | Sep 30, 2016
Traditional stop codons have a double meaning in the protozoans' mRNA, sometimes calling for an amino acid during translation.
