RNA molecules are the mobile messengers of genes. They carry information on the production of proteins from the DNA to the ribosomes. In addition to these messenger RNAs all living beings have micro RNAs that can hinder the messenger RNAs and thus the production of proteins. Biologists have now discovered that such micro RNAs also come into direct contact with genes, effectively turning off the genes in the process.
