About this unit

What exactly is DNA? This seemingly simple polymer, made up of just four different types of monomers, serves as the genetic material for all living organisms. For example, your DNA provides instructions for building and maintaining your unique body and can be passed on if you have children. Learn more about the discovery, structure, and synthesis of this remarkable molecule.
