DNA is a polymer of nucleotides formed by condensation, with phosphodiester bonds between nucleotides. Each nucleotide is formed from a deoxyribose, a organic base and a phosphate group. DNA is a double helix with two polynucleotide 0.4 weeks Explain the significance of DNA to organisms. Describe the structure of DNA and identify structural components from diagrams.
