| Hybridization is based on the annealing properties of DNA
|
| Double-stranded DNA exists in life as a double helix, in which the two strands are held together by the hydrogen bonds between complementary bases (A with T, and G with C).
|
| Hybridization is a fundamental feature of DNA technology. It is a process by which a piece of DNA or RNA of known nucleotide sequence, which can range in size from as little as 15 bp to several hundred kilobases, is used to identify a region or fragment of DNA containing complementary sequences. The first piece of DNA or RNA is called a probe. Probe DNA will form complementary base pairings with another strand of DNA, often termed the target, if the two strands are complementary, and a sufficient number of hydrogen bonds is formed.
