In order to understand the forces that have shaped transcripts during evolution, one has to study mutation patterns associated with transcription across animals.
Web Tool available at: http://mirna.imbb.forth.gr/MatureBayes.html MicroRNAs (miRNAs) are small, usually 19 27 nucleotides long, single-stranded RNAs that are generated from endogenous hairpin shaped transcripts [1].
In the economy of the yeast cell, we find that the cost of amino acid synthesis plays a limited role in shaping transcript and protein expression levels compared to that of translational optimisation.
The expression of FAD8 was characterized by a bell-shape transcript curve, with low levels of expression at the initial stage followed by a substantial increase during the rapid phase of oil accumulation and a subsequent decline toward seed maturation.
These sequential actions require superseding the transcripts, buffering the noise from unintended transcripts, and shaping the transcriptional output to fit the context or keep homeostasis.
If transcription of one gene were to continue past the normal termination site and into the neighboring gene, the result might be a long hairpin-shaped transcript that is capable of generating sRNAs that target one or both genes.
Monologues were shaped using verbatim transcripts of interviews.
During gene expression, protein-coding transcripts are shaped by multiple processing events: 5′ end capping, pre-mRNA splicing, RNA editing, and 3′ end cleavage and polyadenylation.
The high frequency of plant-specific genes that are important for chloroplast RNA homeostasis demonstrates that transcript regulation has shaped the emergence of plant-specific expression systems for components of the plastid.
Previous studies have indicated that RNA stability influences the abundance of transcript and shapes the kinetics of gene induction in intricate gene networks in mammalian cells [ 13- 16].
Of these 76 genes, 21 overlapped a 5% outlier F ST window, supporting the hypothesis that spatially varying selection plays an important role in shaping geographic differences in transcript abundance for genes related to locomotion/circadian rhythms.
