We found that the combination of spatially restricted uracil phosphoribosyltransferase (UPRT) expression with 4-thiouracil delivery can be used to label and purify cell type-specific RNA from intact complex tissues in Drosophila melanogaster. This method is useful for isolating RNA from

Dinoflagellates possess many physiological processes that appear to be under post-transcriptional control. However, the extent to which their genes are regulated post-transcriptionally remains unresolved. To gain insight into the roles of differential mRNA stability and de novo transcription in dinoflagellates

The 'RNA world' hypothesis proposes that early life developed by making use of RNA molecules, rather than proteins, to catalyse the synthesis of important biological molecules. It is thought, however, that the nucleotides constituting RNA were scarce on early Earth.

Intensified research interests are posed with the thionucleobase 4-thiouracil (4-TU), due to its important biological function as site-specific photoprobe to detect RNA structures and nucleic acid-nucleic acid contacts. By means of time-resolved IR spectroscopy and density functional theory (DFT) studies
