The DNA structure is a marvel of biological engineering, consisting of a double helix formed by two strands of nucleotides connected through hydrogen bonds, as depicted in the image. This iconic structure is fundamental to life, encoding genetic information that dictates the development and functioning of all living organisms. By examining its key components—nitrogenous bases, base pairs, and the sugar-phosphate backbone—this article provides a detailed look into the anatomical and physical properties of DNA, offering insights into its role in heredity and molecular biology.
