DNA PROBE


In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length (usually 100-1000 bases long), which is used in DNA or RNA samples to detect the presence of nucleotide sequences (the DNA target) that are complementary to the sequence in the probe. …
(DNA probes) Species- or subspecies-specific DNA (including COMPLEMENTARY DNA; conserved genes, whole chromosomes, or whole genomes) used in hybridization studies in order to identify microorganisms, to measure DNA- DNA homologies, to group subspecies, etc. …
Short piece of DNA that is complementary to a specific piece of DNA in the cell. By marking the probe, it is possible to visualize whether the DNA is present in the genetic material. This forms the basis for DNA diagnostics.
A chemically synthesized, often radioactively labeled, segment of DNA used to visualize a genomic sequence of interest by hydrogen-bonding to its complementary sequence.
A molecule that has been labeled with a radioactive isotope, dye or enzyme and is used to locate a particular portion of a DNA molecule.
a radioactive or fluorescent labelled (tagged) segment of single-stranded DNA used in hybridisation and other studies to detect a specific DNA sequence. If the tagged sequence is complementary to any one in the mixture, the two sequences will form a double strand and be difficult to separate
a piece of single-stranded DNA, typically labelled so that it can be detected (for example, a radioactive or fluorescent label can be used), which can single out and bind with (and only with) another specific piece of DNA. …
