“Deoxyribonucleic acid, or DNA is the molecule that transports most genetic instructions utilized in the growth, function and biological process of all living organisms and many viruses.” (Merriam-Webster Dictionary) It was first discovered at the University of Tübingen by Friedrich Miescher in 1869. Miescher discovered DNA through a microscopic substrate in a sample of pus on unwanted surgical gauze. (Dahm)
Nature is a scientific journal in Britain, where studies and academic research in scientific fields are published. In 1953, Francis Crick and James D. Watson published a scientific article describing the molecular structure of DNA. They also described the detection a double-helix, using scientific data collected by Rosalind Franklin and Maurice Wilkins. With the use of X-ray diffraction and mathematics of a helix transform, Crick and Watson were able to figure out the DNA’s structure. (Nature 171)
The structure of DNA is the double-helix discovered by Watson and Crick. The discovery of this made it possible to understand that genes are the defined parts of DNA molecules. The building blocks paired specifically with each other and are called nucleotides. Nucleotides are organic molecules that help as monomers of nucleic acids like DNA. They also help carry energy inside the cell. (Watson JD, Crick FH)
Guanine, cytosine, adenine, and thymine are the nucleobases found in the DNA. The guanine amount is the same as cytosine and the amount of adenine is the same for thymine.…
