Making a Splash: Researchers Apply Face-Detection Technology to the Study of Genes

Between the DNA that stores our genetic information and the proteins that build our cells lies RNA — the middleman that relays the instructions. It carries genetic information out of the cell nucleus and into the cytoplasm. There, it’s translated into proteins, the movers and shakers that actually control what happens in our bodies.

Because RNA allows that all-important leap from DNA to protein, it’s a useful target for laboratory researchers who are interested in identifying the functions of genes. Using a technique called RNA interference (RNAi), researchers can selectively destroy particular RNA transcripts to “knock down” specific genes. Without the RNA transcript, the protein is no longer made.
