  "textContent": "A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over how genes are expressed. Human DNA stores instructions for life in sequences built from just four nucleotides. Those instructions are read in three-letter groups called codons, and each codon tells the cell which amino acid to [...]",
