The Structure of DNA (book)

"The Structure of DNA" explains how DNA, the molecule carrying genetic information, is organized. DNA is made up of two long strands forming a double helix, resembling a twisted ladder. The sides of the ladder are composed of sugar and phosphate molecules, while the rungs are pairs of nitrogenous bases (adenine, thymine, cytosine, and guanine) that connect across the strands. Base pairing follows specific rules (e.g., A with T, C with G). This structure allows DNA to store, replicate, and transmit genetic instructions accurately, forming the foundation of life’s diversity and inheritance.
