Question
Which color of light excites a natural GFP to emit green fluorescence?(A) Blue(B) Green(C) Infrared(D) RedQ.8 Which one of the following hormones promotes fruit ripening?(A) Abscisic acid(B) Auxin(C) Ethylene(D) Gibberellin
Solution
The color of light that excites a natural GFP (Green Fluorescent Protein) to emit green fluorescence is (A) Blue. This is because GFP absorbs light in the blue region of the visible spectrum (around 395 nm to 475 nm) and emits light in the green region (around 509 nm).
The hormone that promotes fruit ripening is (C) Ethylene. Ethylene is a gaseous plant hormone that regulates a wide range of biological processes in plants. It is especially known for its role in stimulating the ripening of fruits.
