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 ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

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

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 ...

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.
