COT Curve Analysis Explained | DNA Reassociation Kinetics | CSIR-NET, GATE, TIFR and CUET-PG

Understanding the C₀t (Cot) Curve is one of the most important concepts in Molecular Biology, Genome Organization, and DNA Hybridisation, especially for CSIR-NET Life Science, GATE XL, DBT-BET, CUET PG, and MSc Biotechnology/Biosciences examinations. In this comprehensive lecture, we will cover the complete theory, derivation, calculations, and interpretation of the C₀t curve, beginning from DNA denaturation to reassociation kinetics. Every concept is explained step-by-step with graphical analysis and numerical examples to build conceptual clarity. 📚 Topics Covered Introduction to DNA reassociation kinetics What is the C₀t value? Principle behind the C₀t experiment DNA denaturation and renaturation Second-order reaction kinetics of DNA reassociation Mathematical derivation of the Cot equation Cot curve plotting and interpretation Cot½ (Cot Half) calculation Relationship between Cot½ and genome complexity Single-copy DNA vs repetitive DNA Highly repetitive, moderately repetitive and unique DNA sequences Genome organization in prokaryotes and eukaryotes Effect of DNA concentration on reassociation Effect of fragment length Effect of salt concentration and temperature Practical numerical problems Previous year CSIR-NET conceptual questions Important examination tricks and shortcuts 🎯 Who Should Watch?
