Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

Specialized silencing systems evolved in eukaryotic lineages through proliferation and specialization of small-RNA biogenesis and effector factors. Genomes spawn new types of RNA silencing ...

New research challenges previous assumptions about RNA transport, finding that RNA can carry instructions across generations.

The Nobel Prize in Medicine was awarded on Monday to two US scientists for discovering microRNA, a previously unknown type of genetic ... Ribonucleic acid (RNA) normally serves as a messenger.

Researchers uncover key mechanisms in gene regulation that may lead to better design of RNA-based medicines.
