Chapter Overview
Biomolecules is the sixth chapter of Class 9 Biology. It focuses on the chemical foundation of living organisms. Students are introduced to the major types of biomolecules—Carbohydrates, Proteins, and Lipids—and learn about their structures, sources, and vital roles in maintaining life processes.
The chapter provides a detailed look at Nucleic Acids, the molecules responsible for storing and transferring genetic information. Students explore the structure of DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid), understanding their differences and how they work together in the cell.
A significant portion of the chapter is dedicated to the Working of DNA and RNA. It explains the central dogma of molecular biology, illustrating how genetic instructions in DNA are transcribed into RNA and translated into proteins. Grasping these fundamental molecular concepts is essential for students to perform well in concept-based board exam questions.
