The DNA sequence contains the instructions to place units called amino acids into a specific order. When these amino acid are assembled in that specific order, proteins are made. In short, DNA contains the instructions to create proteins. Each strand of DNA has many separate sequences that code for a specific protein. Insulin is an example of a protein made by your cells. Units of DNA that contain code for the creation of a protein are called genes. Learn more about protein synthesis and gene expression in this learning module produced by CK-12.

Learn about the molecular structure of RNA. [11:30]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
How does DNA perform those all-important functions of replication and protein synthesis? This interactive feature, from the Web site developed for the PBS series "A Science Odyssey," will help you explore and understand the secrets of DNA.
Use this simulation to create three different proteins, then explore the process of protein synthesis. This simulation must be downloaded and requires Java to run. Available in numerous languages.
Generate and collect three types of proteins, then move on to explore the factors that affect protein synthesis in a cell.
