DNA or RNA segment tagged with a radioactive molecule is called
Probe is a defined nucleic acid molecule that can be used in molecular hybridization procedures to
identify specific nucleic actd sequences that are complementary to it, by virtue of a label carried by
the probe. The label may be radioactive or non-radioactive. Nuclei add probes have a wide range of
applications such as in the detection of microorganisms in clinical specimens, in food and water
samples, in the detection of genctic diseases, etc.
