Haven’t we all heard about DNA, the genetic material that makes who we are? Short for Deoxyribonucleic acid, the DNA is made of two chains that coil around each other forming the double helix structure as we know it today. Although Friedrich Miescher first isolated the DNA molecule in 1869, it was not until 1953 that we understood its structure. Two scientists, James Watson and Francis Crick, are well-known for showing us the double-helix structure of the DNA.
