    • 8.1: Nucleic Acids - Structure and Function
      Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life. The nucleic acids consists of two major macromolecules, Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that carry the genetic instructions for the development, functioning, growth and reproduction of all known organisms and viruses.
    • 8.2: Nucleic Acids - RNA Structure and Function
      Ribonucleic acids are very similar in chemical structure to DNA except they contain ribose instead of deoxyribose. They also have the pyrimidine base uracil instead of thymine. These two small changes (but mostly the first) confer on it a very different set of biological functions than DNA. This should not surprise us and the basis of all chemistry and biochemistry is that chemical structure determines chemical and biochemical functions and activities.
    • 8.3: Nucleic Acids - Comparison of DNA and RNA
      Now that we have an understanding of the structures of DNA and the structures and various functions of RNA, we can now more fully explore how their chemical similarities and difference contribute to different functions.
