A recent <i>Nature<\/i> <a href=\"https:\/\/www.nature.com\/articles\/s41586-026-11200-4\" target=\"_blank\">study<\/a> investigated whether this protein-building glitch in cancer cells can be turned into a targeted cancer therapy.<\/p>\n<p>Ribosomes read mRNA in groups of three genetic letters, known as codons.
