It said that DNA was made up of four bases (adenine, thymine, guanine and cytosine) that were present in regular amounts, but that their organisation was too simple to carry hereditary information. It was Chargaff's work that overturned this.rwin Chargaff. Erwin Chargaff was working at Columbia University in New York in the 1940s when he read Oswald Avery's research about DNA being the hereditary material. From that moment in 1944 he devoted his research to working out the chemical composition of DNA.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.eoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.
