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:)

Who made DNA probes?
DNA probes were first developed by researchers in the 1970s, with significant contributions from scientists such as Edwin Southern, who created the Southern blot technique. This method allowed for the identification of specific DNA sequences within a complex mixture. The development of DNA probes has since advanced significantly, playing a crucial role in molecular biology, genetics, and medical diagnostics.
Why is pure culture not used for DNA probes?
Pure cultures are typically not used for DNA probes because the probes need to target specific genetic sequences that may not be present in a single organism. Environmental samples often contain a diverse array of microorganisms, and DNA probes are designed to detect specific genes or sequences in complex communities. Additionally, using pure cultures may miss interactions and functions that occur in mixed populations, which are more representative of natural settings. Thus, probes are often designed to target sequences from multiple species to accurately reflect the biodiversity of the environment.
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.
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.

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.
