Levels of Organization Image Map
Proteins are needed to make structures in the cell and to serve in a variety of ways as signaling molecules. The making of protein is directed by the genes on chromosomes inside the cell nucleus.

Outside the nucleus, protein is constructed by several "manufacturing" steps, beginning in the organelle known as the ribosome and ending in the organelle known as the Golgi complex..

Making A Protein Chart

After completing this lesson, each student should be able to:

  1. Explain what proteins are like and why they contain an information code.
  2. Distinguish between the levels of protein structure—and explain how denaturation works.
  3. Summarize what proteins do, with examples.
