How DNA carries the instructions for making proteins

Learn how a sequence of four DNA bases is copied and read, three bases at a time, to build the proteins that run every cell.

In lesson one, the nucleus controlled the cell by controlling which proteins it makes. In lesson two, enzymes drove every step of photosynthesis, and enzymes are proteins. So where do the instructions for proteins come from? They are written in DNA. This lesson explains how a chemical code becomes a working protein.
