The big role of small RNAs

Small, or non-coding, RNAs do not carry information about the structure of the protein, but are associated with the most important processes in the life of both the cell and the whole organism. Knowledge about the role of small RNAs in the transmission of hereditary information and in the development of cancerous tumors will help to move faster from the first model experiments to applied medical research.
