Molecular Basis of Inheritance — NEET/JEE Questions, Notes & Weightage
Class 12 Genetics and Evolution NEET weightage: Very High 4,142 questions
Covers DNA structure and replication, transcription, the genetic code, translation, gene regulation (lac operon), and the Human Genome Project. Extremely dense with independently testable facts — DNA replication enzymes and the genetic code properties are tested almost every year.

Frequently asked questions
What makes this chapter so heavily tested?
It covers the entire central dogma (DNA → RNA → protein) in mechanistic detail, with named enzymes, structures, and processes at every step — each one independently quizzable.
What properties of the genetic code does NEET ask about?
Degeneracy, universality, and the specific start/stop codons (AUG, UAA/UAG/UGA) are the most frequently tested genetic-code properties.
Is the lac operon really asked in NEET?
Yes — the lac operon is the standard example NEET uses to test gene-regulation concepts (inducer, repressor, structural genes), and it appears regularly.
