    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 replicated genetic information:

    illustration of a segment of DNA. The molecule is composed of two helixes, which spiral in opposite directions from one another. The two helixes are connected by "ladder rungs" of adenine, thymine, cytosine, and guanine.

    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.
