Ted: Ted Ed: Rn Ai: Slicing, Dicing and Serving Your Cells
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...

Biology Wise: Start Codon
A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.

Biology Wise: What Is a Stop Codon?
A stop codon is a nucleotide triplet in messenger RNA that signals the end of a protein during the translation process. Read about how this works, the different types of stop codons, and how a mutation can sometimes occur.
