"A lot of the regulatory puzzles in E. coli are explained by small RNA's we didn't think were there."

The recent excitement has been generated by two discoveries related to small RNA snippets and their ability to turn off genes.

As research continues, scientists wonder how the small RNA's eluded them for so long.

Recently it has been discovered that small RNA can trigger specific gene silencing in human cells.

Recently researchers in his laboratory demonstrated the detection and sizing of the smallest individual RNA virus.

This small RNA was found to function as a microRNA.

The spontaneous assembly of small RNA molecules on the primitive earth "would have been a near miracle," two experts in the subject helpfully declared last year.

It is believed not to be a cis-acting element, but a small RNA.

This small RNA was shown to be bound by the Hfq protein.

In type I toxin-antitoxin systems, the gene expression of a toxic protein is regulated by a small non-coding RNA.
