The Nature of DNA

DNA, or deoxyribonucleic acid, is the molecule that contains the genetic instructions for all living organisms. It’s made up of two strands forming a double helix, composed of four types of building blocks called bases. The sequence of these bases encodes the information needed to build and operate an organism. DNA is like a biological blueprint, guiding the development, functioning, and reproduction of cells. It’s found in the nucleus of cells and is essential for heredity, passing genetic traits from parents to offspring. Overall, DNA provides the fundamental code that defines living beings.
