Any biochemistry, chemistry, & science nerd will love this DNA tie clip! Deoxyribonucleic acid (DNA) is a long polymer made from repeating units called nucleotides. A DNA molecule carries the genetic instructions used in the growth, development, functioning & reproduction of all known living organisms & many viruses. DNA & RNA are nucleic acids; alongside proteins, lipids & complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. Its structure is dynamic along its length, being capable of coiling into tight loops & other shapes.
