The question became how to study the dna molecule biochemists believed that understanding its structure would reveal how the molecule coded the instructions for copying a new organism they began taking x-ray images of crystals of dna, believing that its crystallization meant it must have a regular structure. In the history of dna, the eugenics movement is a notably dark chapter, which highlights the lack of understanding regarding the new discovery at the time the term 'eugenics' was first used around 1883 to refer to the science of heredity and good breeding . Watson and crick describe structure of dna watson and crick showed that each strand of the dna molecule was a template for the other dna's discovery has been called the most important .

The discovery of dna surely, one type of molecule could not account for all the variation seen within species the four building blocks of dna. The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (dna), by james watson and francis crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells.
