DNA hybridization




A method of comparing the DNA from different organisms in order to discover genetic relationships between species. Single strands of DNA from each species are placed together and allowed to react. Some strands will "hybridize" to form double strands (the usual structure of DNA) and the extent to which they do so indicates how many base sequences are complimentary. This in turn is a measure of how similar the genes are.
