What is DNA, again? This educational diagram explains DNA as a polymer made of repeating nucleotides, each consisting of a simple sugar, a phosphate group, and a nitrogenous base, with a visual representation of the double helix structure and base pairing.
Diagram illustrating the structure of DNA, showing a double helix with labeled components including nucleotides, nitrogenous bases (adenine, thymine, cytosine, guanine), sugar-phosphate backbone, and base pairing (A-T, C-G).
