Introduction to Storing Genetic Information

What you’ll learn to do: Explain how DNA stores genetic information

The unique structure of DNA is key to its ability to store and replicate genetic information:

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