Chapter 9: Molecular Biology
Chapter Overview
Learning Objectives
By the end of this chapter, you will be able to:
- Explain the historical significance of the discovery of DNA as the genetic material and identify key scientists involved in uncovering DNA’s structure.
- Describe the molecular structure of DNA, including the role of nucleotides, sugar-phosphate backbone, nitrogenous bases, and the double helix formation.
- Differentiate between purines and pyrimidines, and identify the rules of complementary base pairing (A-T and G-C).
- Define antiparallel strands and explain the significance of the 3′ and 5′ ends of DNA.
- Summarize the process of DNA replication, including where and when it occurs in the cell cycle and how the structure of DNA allows it to be copied during DNA replication.
- Identify the roles of key enzymes involved in DNA replication, such as DNA polymerase, and describe their function.
- Describe how replication bubbles form and expand during the process of DNA replication.
- Relate the importance of accurate DNA replication to growth, development, and cellular function in multicellular organisms.
