Molecular Basis of Inheritance
A single fertilised egg holds the whole plan of a person, written in a molecule so thin that two metres of it fit inside a nucleus. How did scientists find out that this molecule, and not a protein, carries the plan? In this chapter you follow the experiments that settled it and then build the double helix, base by base. You see how it is packed, how it is copied before a cell divides, how a gene is read into RNA and how the RNA is turned into a protein. You also meet the switch that lets a bacterium use lactose only when it is there, the project that read the whole human genome, and the DNA fingerprint. It serves the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP. Python counts bases, codons and generations.
