Lariat RNA's as Intermediates and Products in the Splicing of Messenger RNA precursors

Science, 1984
The splicing of messenger RNA precursors in vitro proceeds through an intermediate that has the 5′ end of the intervening sequence joined to a site near the 3′ splice site. This lariat structure, which has been characterized for an adenovirus 2 major late transcript, has a branch point, with 2′-5′ and 3′-5′ phosphodiester bonds emanating from a single ...

Photochemistry of RNA, RNA Monomers, and Plausible Prebiotic Precursors

, 2023
Sunlight is the primary source of energy to promote change on Earth. In this context, ultraviolet radiation can be thought as a catalyst of chemical change to refine chemical feedstocks and facilitate their transformations into the building blocks of life. To establish reasonable environmental constraints for the chemical origins of life, it is central

Dimeric transfer RNA precursors in S. pombe

Cell, 1980
Sequence analysis of a Schizosaccharomyces pombe DNA fragment revealed two tRNA coding regions separated by a seven nucleotide spacer. the 5'-proximal tRNA gene encodes a tRNAUCGSer sequence, which is interrupted by a 16 nucleotide intron at the 3' side of the base adjacent to the anticodon.

Transcription and Processing of Transfer RNA Precursors

Progress in Nucleic Acid Research and Molecular Biology, 1976
Publisher Summary This chapter discusses the transcription of tRNA genes as precursors and how these are converted to mature tRNA. One important step in tRNA biosynthesis, the modification of tRNA bases, is discussed only in relation to the precursors.

Characterization of the ribosomal RNA precursor in Ilyanassa

Experimental Cell Research, 1972
Abstract Ilyanassa embryos synthesized a high molecular weight, rapidly-labeled RNA species that, as time progressed, diminished in proportion to increasing amounts of nascent ribosomal RNA. We tentatively identify this rapidly-labeled RNA species as the ribosomal RNA precursor.

Multiple conformations of ribosomal precursor RNA

Nature, 1975
WE wish to propose an explanation for the heterogeneity shown1 by ribosomal precursor RNAs on gel electrophoresis. The clearest demonstration of this phenomenon is shown in Fig. 1. 32P-labelled RNA was eluted from single gel slices taken across the peak, and rerun in the presence of 3H-labelled marker.
