Quizplus · Accepted Answer

DNA probes are single-stranded sequences of DNA that are labeled with a detectable signal (such as a fluorescent dye) and are used to find specific complementary sequences of DNA. By hybridizing to the target DNA, the probe can reveal the presence and location of the complementary sequence, for example in a Southern blot or fluorescence in situ hybridization (FISH) assay.
