Mitochondrial DNA (mtDNA) is more plentiful and durable than nuclear DNA, making it a valuable alternative for analysis when nuclear DNA is degraded or damaged. This is because mitochondria, and thus mitochondrial DNA, are present in much higher numbers in cells compared to the two copies of nuclear DNA. Additionally, the circular structure of mtDNA contributes to its durability.
