DNA and RNA segment tagged wit Â a radioactive molecule is called

• vector

• probe

• clone

• plasmid

B.

probe

The probe is a defined nucleic acid molecule that can be used in molecular hybridization sequence that is complementary to it, by virtue of a label carried by the probe. The label may be radioactive or non- radioactive. Nucleic acid 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 genetic diseases, etc.
