Class 12 Biology NCERT Molecular Basis of Inheritance
The chapter Molecular Basis of Inheritance in Class 12 NCERT Biology explores the molecular mechanisms by which genetic information is stored, replicated, and expressed. Students learn about DNA structure and replication, RNA types, and the central dogma of molecular biology: transcription and translation. The chapter also covers genes, genetic code, protein synthesis, and regulation of gene expression, along with experiments that proved DNA as the hereditary material.
NCERT provides detailed explanations, diagrams, and solved examples to strengthen conceptual understanding. This chapter is crucial for CBSE Class 12 board exams and competitive exams like NEET, where questions on molecular genetics are frequently asked. By mastering Molecular Basis of Inheritance, students gain insights into how genetic information governs cellular function, heredity, and evolution. Regular study and diagram labeling improve retention and performance in both theoretical and application-based questions.
