Teach me about DNA.
Understand the Problem
The question is asking for information and explanation about DNA, including its structure, function, and importance in biological systems.
Answer
DNA is a molecule containing genetic information essential for life, structured in a double-helix.
DNA, or deoxyribonucleic acid, is a complex molecule that contains genetic information necessary to build, develop, and maintain living organisms. It is found in nearly every cell of a multicellular organism and is structured in a double-helix shape, composed of nucleotides.

More Information
DNA is often described as a blueprint or recipe that guides the development and functioning of living organisms. The double-helix structure, discovered by Watson and Crick, is critical to its function of storing and transmitting genetic information.
Tips
A common misconception is thinking all DNA is identical; while chemically similar, different organisms have unique genetic sequences.
