DNA - Structure, Function, and Replication

James Watson and Francis Crick accurately described the structure of DNA as a double helix. Before you learn more about the structure of DNA in this topic, take a moment to create a sketch of what you believe the double helix structure of DNA to look like. Consider the following questions as you create your sketch: How are the strands connected? What are the subunits of DNA? Are you able to label any of the parts of the molecule? Save your sketch to refer back to at the end of this topic.
