Abstract

We describe a method for the synthesis of microgram quantities of eucaryotic messenger RNAs. Injection into the cytoplasm of frog oocytes and addition to wheat germ extracts show that these synthetic RNAs function efficiently as messenger RNAs. We confirm that a 5' cap on the mRNA is essential for translation in injected oocytes and show that most of the 3' flanking region, including the poly A tail, can be deleted without the abolition of protein synthesis. The method of mRNA synthesis involves in vitro transcription of cDNAs which have been cloned into SP6 vectors (described in the accompanying paper). This method enables one to produce large amounts of mRNA and consequently protein from any cDNA clone.

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.
