For the location/detection of a gene in a DNA library which of the following is used?
Correct answer: B. Probe
- A. Primer
- B. Probe
- C. Restriction enzyme
- D. Taq Polymerase
Explanation
Aprobe is a single-stranded sequence of DNA or RNA used to search for its complementary sequence in a sample genome. DNA probes are important tools in diagnostics to ensure high specificity and sensitivity. They are used in molecular biology methods like PCR. Fluorescence in situ hybridization (FISH) is a laboratory technique for detecting and locating a specific DNA sequence on a chromosome. The technique relies on exposing chromosomes to a small DNA sequence called a probe that has a fluorescent molecule attached to it.
