Across the tree of life, ribosomes, the tiny protein-producing factories within cells, are ubiquitous and look largely identical. Ribosomes that keep bacteria chugging along are, structurally, not much different from those churning out proteins in our own human cells.
But even two organisms with similar ribosomes may display significant structural differences in the DOI: 10.1038/s41586-022-05621-0
