Final answer:
The name of the fluorescent protein obtained from a jellyfish that can be used to track specific proteins in cells is green fluorescent protein (GFP). GFP absorbs blue or ultraviolet light and emits green light to reveal the location of proteins within cells.
Step-by-step explanation:
The name of the fluorescent protein that is obtained from a jellyfish and can be used to follow a specific protein through the cell and reveal the dynamic activities in which that protein participates is green fluorescent protein (GFP).
GFP was first identified in the jellyfish Aequorea victoria and is widely used in biological research as a genetic marker. It absorbs blue or ultraviolet light and emits green light, allowing scientists to track the movement and localization of proteins in living cells.
For example, GFP can be fused to a target protein and expressed in cells. When illuminated with the appropriate wavelength of light, the fused protein will fluoresce and reveal its location within the cell.
