DNA makes RNA makes Protein
DNA is "read" by a polymerase enzyme to make a messenger RNA (mRNA). Biologists call this process transcription.

The mRNA from various genes is "read" by the ribosome to make various proteins. Biologists call this process translation.
Proteins are chains of amino acids. The sequence of amino acids along this chain is very important. The sequence determines the shape of the protein.

Example protein: Cytochrome C
