Just a few decades ago, ribonucleic acid (RNA) molecules were considered simple intermediaries between DNA, the protagonist of genetics, and proteins, the products of genes. RNA is now proving to play an important role in gene transcription and regulation, processes which are key to understanding how an organism develops and functions.

The study of ribonucleic acid molecules has provided many surprises, the most revolutionary being the mechanism of gene silencing, or RNA interference (RNAi). This discovery has had far-reaching repercussions in laboratories across the world, not only because the novelty of the mechanism, but also because it has enormous potential for clinical...
