Explanation:
Detailed explanation-1: -DNA probes are often used to detect, in a complex mixture of nucleic acids, only those molecules with sequences that are complementary to all or part of the probe.
Detailed explanation-2: -In molecular biology, a hybridization probe (HP) is a fragment of DNA or RNA of usually 15–10000 nucleotide long which can be radioactively or fluorescently labeled.
Detailed explanation-3: -The gene probes are usually labeled with radioactive or fluorescent material. The radioactive tag allows the visualization of the DNA binding. It could bind to a cell or a chromosome within the sample. The DNA or RNA fragment from the probe interacts with a complementary sequence of a target nucleic acid.
