Describe the technique of fluorescence resonant energy transfer (FRET) and its purpose
What will be an ideal response?
Ans: FRET is a type of real-time PCR that can be used to quantify the amount of amplicon product formed at any time during the reaction. It relies on two fluorophores, a "reporter" and a "quencher." One of each is attached to each of the two probes that are specific for the correct PCR product. When the correct product is formed, the two are in close proximity, and reporter excites the quencher to fluoresce. When the correct product is not formed, the two remain separate and only the reporter will fluoresce.
