Biology
Molecular Basis of Inheritance
वंशागति का आणविक आधार
This Class 12 Biology chapter explains how hereditary information is stored, copied, expressed, and passed from one generation to the next. Students explore the structure of DNA and RNA, DNA replication, transcription, translation, the genetic code, and gene regulation. It also introduces mutations, the lac operon, the Human Genome Project, and DNA fingerprinting, helping learners connect molecular processes with inheritance, variation, biotechnology, and biological identification.
