DNA hybridization probe


Gene Machine or mRNA or similar gene from another organism

Description and Procedure:

This probe is a single stranded piece of radioactive DNA (or RNA) that is complementary to part of the DNA fragment of interest. When added to the target DNA the probe will hydrogen bond to it. An autoradiograph gives away the position of the probe and its target. See Access Excellence Nucleic Acid Hybridization.

Uses or Function:

Used to locate a specific gene or fragment from a large gene library.
