Secondary structure RNA elements control the cleavage activity of DICER
MicroRNA precursors are cleaved by DICER to generate mature microRNAs in the cytoplasm. Here the authors employ high-throughput analysis of DICER cleavage activity and identify RNA secondary elements in precursor miRNAs and shRNAs, including a single ...

Polyadenylation of stable RNA precursors in vivo [PDF]
Polyadenylation at the 3′ terminus has long been considered a specific feature of mRNA and a few other unstable RNA species. Here we show that stable RNAs in Escherichia coli can be polyadenylated as well. RNA molecules with poly(A) tails are the major products that accumulate for essentially all stable RNA ...

Assessing the Gene Content of the Megagenome: Sugar Pine (Pinus lambertiana). [PDF]
Sugar pine (Pinus lambertiana Douglas) is within the subgenus Strobus with an estimated genome size of 31 Gbp. Transcriptomic resources are of particular interest in conifers due to the challenges presented in their megagenomes for gene identification ...

Structural determinants of Arabidopsis thaliana Hyponastic leaves 1 function in vivo. [PDF]
MicroRNAs have turned out to be important regulators of gene expression. These molecules originate from longer transcripts that are processed by ribonuclease III (RNAse III) enzymes. Dicer proteins are essential RNAse III enzymes that are involved in the

Description Generation using Variational Auto-Encoders for precursor microRNA [PDF]
Micro RNAs (miRNA) are a type of non-coding RNA, which are involved in gene regulation and can be associated with diseases such as cancer, cardiovascular and neurological diseases. As such, identifying the entire genome of miRNA can be of great relevance.

Systematic identification of abundant A-to-I editing sites in the human transcriptome [PDF]
RNA editing by members of the double-stranded RNA-specific ADAR family leads to site-specific conversion of adenosine to inosine (A-to-I) in precursor messenger RNAs. Editing by ADARs is believed to occur in all metazoa, and is essential for mammalian development.

Towards RNA life on Early Earth: From atmospheric HCN to biomolecule production in warm little ponds [PDF]
The origin of life on Earth involves the early appearance of an information-containing molecule such as RNA. The basic building blocks of RNA could have been delivered by carbon-rich meteorites, or produced in situ by processes beginning with the synthesis of hydrogen cyanide (HCN) in the early Earth's atmosphere.

Pseudouridylation of yeast ribosomal precursor RNA
The pseudouridylation of ribosomal RNA of Saccharomyces carlsbergensis was investigated with respect to its timing during the maturation of rRNA and its sequence specificity. Analysis of 37-S RNA, the common precursor to 17-S, 5.8-S and 26-S rRNA and most probably the primary ribosomal transcript, shows that this RNA molecule contains already most if ...

Hfq and RNase R Mediate rRNA Processing and Degradation in a Novel RNA Quality Control Process
RNA quality control pathways are critical for cell survival. Here, we describe a new surveillance process involved in the degradation of highly structured and stable ribosomal RNAs.
