dna dna hybridization
DNAâDNA hybridization generally refers to a molecular biology technique that measures the degree of genetic similarity between pools of DNA sequences. It is usually used to determine the genetic distance between two organisms.This has been used a lot in phylogeny and taxonomy.he DNA of one organism is labeled, then mixed with the unlabeled DNA to be compared against. The mixture is incubated to allow DNA strands to dissociate and renewal forming hybrid double-stranded DNA.
