  1. Question 1

    Q1. A medical researcher uses fluorescence spectroscopy to analyze the binding of a protein to a specific DNA sequence. What type of fluorescence is observed during this process?

    • A) Fluorescence resonance energy transfer (FRET)
    • B) Autofluorescence
    • C) Quenching of fluorescence
    • D) Enhancement of fluorescence

    Answer: Fluorescence resonance energy transfer (FRET)

    Explanation: Fluorescence resonance energy transfer (FRET) is observed during the binding of the protein to the DNA sequence, as it represents the transfer of energy from one molecule to another.
