Chapter 28: Nucleosides, Nucleotides and Nucleic Acids

Summary

• Nucleic acids are the acids found in cell nuclei and are involved in the transmission of genetic information.
• They are complex biopolymers containing a carbohydrate, a phosphate ester and a heterocyclic aromatic unit, the base.
• There are two types of nucleic acids : ribonucleic acids or RNA, and deoxyribonucleic acid or DNA.

• Pyrimidines and Purines
• Nucleosides
• Nucleotides
• Nucleic acids
• Bioenergetics : ATP
• DNA : DNA replication, Protein Biosynthesis and RNA

• Sample problems
