This study is the first to demonstrate that certain tRNA introns influence gene expression. Scientists have discovered that ...

Proteins that trigger cell senescence occupy much of the literature on aging, but a small RNA moves into the limelight. Kamal is a freelance science journalist based in the UK with a PhD in virology ...

At the cellular level, pieces of important genetic information, called small RNA, have the ability to introduce important ...

Further analysis of the genes transcribed from the genomic island revealed that the 3'UTR of mRNA was processed to generate ManS, a novel small noncoding RNA of 80 nt in length. Importantly, ManS ...

Eukaryotes have evolved small-RNA-guided regulatory systems for the control of RNA transcripts, chromatin, genome content and invasive agents. Specialized silencing systems evolved in eukaryotic ...

and their diversity of functions has led to the hypothesis that an "RNA world" may have preceded the evolution of DNA and proteins (Gilbert, 1986). Small interfering RNAs (siRNAs) are yet another ...

RNA interference (RNAi) is a cellular mechanism that uses small RNA molecules, such as small interfering RNAs (siRNAs) and miRNAs, to silence gene expression. These small RNAs can bind to ...

They say that change takes time. Well, that's not the case for RNA. The small biological molecule acts like a switchboard ...

A new blood test may help detect pancreatic cancer in its early stages with up to 97% accuracy, according to a recent study.

Centrosomes are nonmembrane organelles and responsible for microtubule nucleation and organization. Centrosomal RNAs have been identified in diverse model systems and are known to regulate gene ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...
