Bioinformatics of prokaryotic RNAs
The genome of most prokaryotes gives rise to surprisingly complex transcriptomes, comprising not only protein-coding mRNAs, often organized as operons, but also harbors dozens or even hundreds of highly structured small regulatory RNAs and unexpectedly large levels of anti-sense transcripts. Comprehensive surveys of prokaryotic transcriptomes and the need to characterize also their non-coding c...
متن کاملEvolution of animal Piwi-interacting RNAs and prokaryotic CRISPRs
Piwi-interacting RNAs (piRNAs) and CRISPR RNAs (crRNAs) are two recently discovered classes of small noncoding RNA that are found in animals and prokaryotes, respectively. Both of these novel RNA species function as components of adaptive immune systems that protect their hosts from foreign nucleic acids-piRNAs repress transposable elements in animal germlines, whereas crRNAs protect their bact...
متن کاملBioinformatics Analysis of Small RNAs in Pima (Gossypium barbadense L.)
Small RNAs (sRNAs) are ~20 to 24 nucleotide single-stranded RNAs that play crucial roles in regulation of gene expression. In plants, sRNAs are classified into microRNAs (miRNAs), repeat-associated siRNAs (ra-siRNAs), phased siRNAs (pha-siRNAs), cis and trans natural antisense transcript siRNAs (cis- and trans-nat siRNAs). Pima (Gossypium barbadense L.) is one of the most economically important...
متن کاملDeep sequencing of small RNAs in plants: applied bioinformatics.
Small RNAs, including microRNA and short-interfering RNAs, play important roles in plants. In recent years, developments in sequencing technology have enabled the large-scale discovery of sRNAs in various cells, tissues and developmental stages and in response to various stresses. This review describes the bioinformatics challenges to analysing these large datasets of short-RNA sequences and so...
متن کاملPhosphorothioate-containing RNAs show mRNA activity in the prokaryotic translation systems in vitro.
Phosphorothioate-containing RNAs were generated by transcription of coliphage T7 DNA using the Sp diastereomers of ribonucleoside 5'-O-(1-thiotriphosphates) and T7 RNA polymerase. RNAs in which a single nucleotide was substituted by the corresponding nucleoside phosphorothioate functioned as mRNA in the cell-free translation systems prepared from Escherichia coli and from an extreme thermophili...
