【单选题】What is the advantage of using GFP-tag to visualize specific proteins, instead of staining cells with fluorescent dyes that bind to the target protein?
A.
GFP fusions enable one to track changes in the location of the protein in living cells; staining usually requires fixed cells
B.
GFP fusions enable higher resolution than staining with fluorescent probes.
C.
GFP permits the position of the protein in the cell more precisely than fluorescent probes
D.
GFP fusions are not subject to artifacts; fluorescent probes may introduce background artifacts.
