C0t analysis, a technique based on the principles of DNA reassociation kinetics, is a biochemical technique that measures how much repetitive DNA is in a DNA sample such as a genome. It is used to study genome structure and organization and has also been used to simplify the sequencing of genomes … See more The procedure involves heating a sample of genomic DNA until it denatures into the single stranded-form, and then slowly cooling it, so the strands can pair back together. While the sample is cooling, measurements are … See more C0t filtration is a technique that uses the principles of DNA renaturation kinetics to separate the repetitive DNA sequences that dominate many See more • Cot Analysis: An Overview Mississippi Genome Exploration Laboratory See more Since a sequence of single-stranded DNA needs to find its complementary strand to reform a double helix, common sequences renature more rapidly than rare sequences. Indeed, the rate at which a sequence will reassociate is proportional to the number of … See more It was first developed and utilized by Roy Britten and his colleagues at the Carnegie Institution of Washington in the 1960s.
