What Is a DNA Probe Used For? North Dakota State University defines a DNA probe as a small piece of nucleic acid (typically single-stranded DNA) that is used to detect complementary stretches of DNA. DNA probes used in hybridization experiments are labeled so that they can be visualized.
DNA probe a labeled segment of DNA or RNA used to find a specific sequence of nucleotides in a DNA molecule. Probes may be synthesized in the laboratory, with a sequence complementary to the target DNA sequence. DNA probe A DNA sequence labelled with a radioactive element used to identify the position of a segment with the complementary sequence by ...
DNA probes can be used to locate specific alleles of genes or to see if a person's DNA contains a mutated allele that causes a genetic disorder DNA probes are short strands of DNA, they have a base sequence that is complementary to the base sequence of part of the target allele
DNA probes are small segments of DNA which help to detect the presence of a gene of a long DNA sequence, in a biological systems. These DNA probes are prepared for commercial purposes and are believed to be the most sophisticated and sensitive means to identify genes or specific DNA sequences.
In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length (usually 100–1000 bases long) which can be radioactively labeled. It can then be 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 probe definition, a technique for identifying a segment of DNA, using a known sequence of nucleotide bases from a DNA strand to detect a complementary sequence in the sample by means of base pairing. See more.
DNA probes are tiny little fragments of DNA which have been labeled with radioactive materials with base pairs complementary to the fragments of the VNTR regions of a DNA.These have been used ...
A cDNA probe is a relatively short piece of single-stranded DNA that is designed to find and stick to hybridize a complementary sequence in one or more of the RFLP's.

Probe hybridization assays were one of the earliest diagnostic techniques using nucleic acids as a target. The most commonly used probes are marketed by Hologic Gen-Probe Inc. (Marlborough, Massachusetts) and consist of single-stranded DNA probes tagged with acridinium esters that hybridize to rRNA. Tests are read in a luminometer.
