It seems that nearly all plant and animal cells have the internal machinery to use siRNA in a function to suppress the expression of particular genes. The RNAi machinery appears to have evolved to protect the genome from endogenous transposable elements and from viral infections. RNAi may also have a normal functional role in cells to inhibit the expression of some genes during growth and development.
