Molecular Basis of Inheritance
What carries heredity across generations. This chapter in NCERT Class 12 Biology, Chapter 5, presents DNA structure, replication, transcription, translation, the genetic code, gene expression, operons and genome projects. It follows Griffith, Hershey and Chase, Watson and Crick, and later work that proved DNA is the genetic material. You will learn how sequences become proteins, how regulation switches genes on and off, and why mutations matter for variation and disease.
