  • DNA and RNA
    • DNA
      • deoxyribonucleic acid
      • stores genetic information which is a code for making proteins
      • it's a polymer made from nucleotide monomers
      • found in the nucleus
      • two anti-parallel chains twist into a double helix
        • two polynucleotide chains
          • H bonds between complementary base pairs
            • A-T and C-G
              • two H bonds between A-T; three H bonds between C-G
    • RNA
      • ribonucleic acid
      • transfers genetic information from DNA to ribosomes
        • ribosomes are made from RNA and proteins
      • it's a polymer made from nucleotides
      • shorter polynucleotide chain
      • single strand
    • nucleotides
      • 1 pentose sugar; a phosphate group; a nitrogenous base
      • adenine, thymine, cytosine and guanine

                  • two H bonds between A-T; three H bonds between C-G
      • adenine, uracil, cytosine, guanine

          • ribonucleic acid
          • transfers genetic information from DNA to ribosomes
            • ribosomes are made from RNA and proteins
          • it's a polymer made from nucleotides
          • shorter polynucleotide chain
          • single strand
      • join together to make polynucleotides
        • condensation reaction between phosphate group of 1 and the sugar of another
          • phosphodiester bonds (1 phosphate group and two ester bonds
        • sugar-phosphate chain is the 'backbone'
