hybridization dna

DNA–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 extensively in phylogeny and taxonomy.

Method ·

In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules anneal to complementary DNA or RNA.[1] Though a double-stranded DNA sequence is generally stable under physiological conditions, changing these conditions in the laboratory

In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length (usually 100–10000 bases long) which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances (the RNA target) that are complementary to the sequence in the probe
