Structure of DNA and RNA explains the molecular architecture of nucleic acids that store, transmit, and express genetic information. This category focuses on the chemical composition, structural organization, and functional significance of DNA and RNA, making it suitable for Class 11–12 students, NEET aspirants, and undergraduate learners.

In this section, you will study:

• Chemical composition of nucleotides

• Structure of DNA and its double helical model

• Types of DNA and their structural features

• Structure and types of RNA

• Differences between DNA and RNA

• Base pairing, polarity, and antiparallel nature of nucleic acids

• Historical experiments related to DNA structure

• NCERT-based explanations, diagrams, MCQs, and exam-oriented questions

The content is structured to build strong conceptual foundations, improve diagram-based understanding, and help students perform confidently in school examinations, NEET, and undergraduate assessments.

Develop a clear understanding of DNA and RNA structure to master the molecular basis of heredity and gene expression.
