The chemical repertoire of natural ribozymes
Abstract
Although RNA is generally thought to be a passive genetic blueprint, some RNA molecules, called ribozymes, have intrinsic enzyme-like activity--they can catalyse chemical reactions in the complete absence of protein cofactors. In addition to the well-known small ribozymes that cleave phosphodiester bonds, we now know that RNA catalysts probably effect a number of key cellular reactions. This versatility has lent credence to the idea that RNA molecules may have been central to the early stages of life on Earth.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
