Computers Inside Cells

Researchers have demonstrated construction of ribonucleic acid (RNA) computers inside cells. RNA is a nucleic acid essential to protein synthesis in cells. Scientists have effectively mimicked the cell's normal machinery to build biocomputers that self-assemble and can execute tasks. This extraordinary concept might allow targeted drug delivery, with RNA computers responsive to pathological climates in cells. More here.
