Summary:
- This article discusses the discovery of a new RNA molecule that can limit the production of certain proteins in cells.
- The researchers found that this RNA molecule, called a "small interfering RNA" (siRNA), can bind to and degrade the messenger RNA (mRNA) that carries the instructions for making specific proteins.
- This discovery could lead to new ways to regulate protein levels in cells, which could have important implications for treating diseases where abnormal protein production is a factor.
