Cryo-EM Uncovers How Tiny Protein Enzyme Precisely Trims tRNA

To build proteins, cells rely on a molecule called transfer RNA, or tRNA. tRNAs act like protein-building couriers, where they read the genetic instructions from messenger RNA, mRNA, and deliver the right amino acids to ribosomes, the cell's protein-making factories.
