Cot curve is a technique used to measure the complexity of DNA or a genome. The DNA renaturation is analysed by this method. When the extent of renaturation of DNA is plotted against log Cot , this is called Cot curve. The cot curve technique was discovered by Roy Britten and Eric Davidson in 1960. … Read more
