DNA Structure Explained

The double helix structure of DNA is crucial for its ability to store genetic information, as it represents the lowest energy state for the molecule. Each nucleotide, consisting of a five-carbon sugar, a phosphate group, and a nitrogenous base, links together to form the DNA strands. Understanding this structure not only reveals how DNA maintains stability over time but also highlights the significance of hydrogen bonds between purines and pyrimidines in ensuring the integrity of genetic information.
