RNA Silencing: The Genome's Immune System
Ronald H. A. Plasterk
Genomes are databases sensitive to invasion by viruses.
In recent years, a defense mechanism has been discovered, which turns out to be conserved among eukaryotes. The system can be compared to the
immune system in several ways: It has specificity against foreign
elements and the ability to amplify and raise a massive response
against an invading nucleic acid. The latter property is beginning to
be understood at the molecular level.
