Explain how DNA stores genetic information.

In this outcome, you will learn describe the double helix structure of DNA: its sugar-phosphate backbone of ladder with nitrogenous base “rungs” of ladder.

What You’ll Learn to Do

• Diagram the structure of DNA.
• Relate the structure of DNA to the storage of genetic information.
• Explain how DNA packaging in both eukaryotic and prokaryotic cells protects genetic information.
