Let’s Begin…

RNA, the genetic messenger, makes sure the DNA recipe gives your cells exactly what they ordered. But sometimes that means inhibiting some other RNA that got the recipe wrong. This process is called RNA interference (RNAi), and it acts as a self-correcting system within the complicated genetic kitchen of your body. Alex Dainis explains the importance -- and exciting potential -- of RNAi.

RNAi works because it interferes with the second step of the Central Dogma, the translation of RNA into protein. Explain the process of how DNA is made into protein using an RNA intermediate.
