These are the tiny fragments of single stranded DNA which are labelled with radioactive materials or fluorescing material with base pairs complementary to the fragments of the VNTR regions of a DNA. These are used during electrophoresis or DNA fingerprinting in order to get the position of desired DNA.
For example; a VNTR region has base pair ATG, then the probe has got the base pairs TAC and a radiactive isotope, like P32 is attached to it. Now the probe combines only to those places where there are the VNTR regions. The isotope will now radiate and so the places from where radiations are received only contain the VNTRs. Hence we can specify the region.
hope u'll understand:)

What is difference between DNA probe and primer?
A DNA probe is a single-stranded DNA sequence used to detect complementary sequences, whereas a primer is a short single-stranded DNA sequence used to initiate DNA synthesis during PCR. Probes are used to identify specific sequences in a sample, while primers are used to amplify a specific target sequence.
Molecules that seek out and identify a particular molecule or piece of DNA are referred to as?
Molecules that seek out and identify a particular molecule or piece of DNA are referred to as probes. These probes are commonly used in molecular biology research to detect specific sequences of DNA or RNA. They can be labeled with fluorescent or radioactive markers for visualization.
What is genomic chips?
Genome chips are miniaturized plates containing hundreds of microscopic wells on their surface. These wells contain DNA probes. DNA probes are basically stretches of cDNA from a particular genome. When genomic DNA isolated from an organism is allowed to interact with the cDNA probes, come probes bind to the genomic DNA while others do not (depending on complementarity. A laser light is used to read each well and look at what sequences are bound. This information is valuable to scientists who can determine changes in gene expression based on the information obtained from a gene chip
How does recombinant DNA technology identify the position of a gene on a chromosome?
A probe may be used, a probe is a specific sequence of DNA tracked by using fluorescent dye. This probe, whose base pairs are known, can be added to another set of DNA. where this probe attaches (seen by adding fluorescent dye to probe), the DNA is seen to be complimentary. These probes have the ability to bond to single complementary strands of DNA from samples. This can be used to determine which chromosome and specific position on the chromosome is complimentary to the known probe DNA. this technique is important to identify abnormal gene sequences, by using thes abnormal probes to test for such genes which may be detrimental to human health. see: http://www.hsc.csu.edu.au/biology/options/genetics/3060/genetics_974.html
How do DNA probes work to identify specific genetic sequences?
DNA probes work by binding to complementary sequences of DNA. These probes are designed to match specific genetic sequences, allowing researchers to identify and locate those sequences within a sample. This process helps to identify and study specific genes or genetic mutations.

Rna and DNA probes bind specifically to the single stranded DNA of their target?
true
How are radioactive probes useful for DNA fingerprinting?
Radioactive probes are useful for DNA fingerprinting because they can bind specifically to complementary DNA sequences, allowing scientists to visualize the DNA fragments on an X-ray film. This helps in identifying unique DNA patterns and comparing them between individuals for forensic or paternity testing purposes. Additionally, radioactive probes are highly sensitive and can detect small amounts of DNA, making them a powerful tool for genetic analysis.

How are DNA hybridization experiments conducted?
Hybridization is the key concept here. Just like the 'Lock and Key Concept' that Envelope Enzymes, Dna hybridization Techniques begin with a Construct - the Dna sequence - and is followed by the Complementary Template.'
