Perhaps the most important molecule in all of biology is DNA, deoxyribonucleic acid. We will devote two chapters to this molecule. In addition, the chapters on mitosis (Chapter 12), genetics (Chapter 19) and evolution (Chapter 20) rely on a thorough understanding of DNA.
All living things contain DNA as the storage unit of genetic information. The DNA molecule in every organism has the exact same structure and function. How it is copied by the cell (replication) and how it is interpreted (transcription and translation) may differ in some details; however, the basics are the same in every living entity. We will concentrate on eukaryotic cells in this and the next chapter.
