Phosphate backbone function
WebBoth molecules contain a phosphate backbone and are made up of nucleotides. DNA carries all the information needed for DNA replication and transfer new information to new cells. This information is also needed to make proteins the body needs for various purposes including regulation of DNA replication. WebThis arrangement makes an alternating chain of deoxyribose sugar and phosphate groups in the DNA polymer, a structure known as the sugar-phosphate backbone Chargaff's rules One other key piece of information related to the structure of DNA came from Austrian biochemist Erwin Chargaff.
