The Ribosome: Perfectionist Protein-maker Trashes Errors
Date: 10.1.2009
Johns Hopkins researchers, reporting in the **journal Nature** January 7, have discovered a new "proofreading step" during which the suite of translational tools called the **ribosome** recognizes errors, just after making them, and definitively responds by hitting its version of a "delete" button.
It turns out, the Johns Hopkins researchers say, that the ribosome exerts far tighter quality control than anyone ever suspected over its precious protein products which, as workhorses of the cell, carry out the very business of life.
