Deoxyribonucleic acid, or DNA, has long been hailed as the molecule that holds the blueprint of life. This twisted ladder-shaped molecule, discovered in 1869, stores the instructions needed to build and maintain an organism. But DNA is a dynamic molecule, and recent research continues to unveil its complexities. The Basic Building Blocks: DNA is made up of smaller units called nucleotides. Each nucleotide has three components: Sugar: Deoxyribose sugar forms the backbone of the DNA molecule. Phosphate group: This group links the nucleotides together to form a chain. Nitrogenous base: There are four types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases form the rungs of the DNA ladder and hold the genetic code. [Insert a diagram of DNA structure here, showing the sugar-phosphate backbone, nitrogenous bases, and hydrogen bonds] The Code of Life: The order of the nitrogenous bases in the DNA sequence is the genetic code. Think of it li...
