- To give the protein molecules energy

Answer 1

- To make the proteins easy to see

Step-by-step explanation:

A fluorescent molecule is the one that exhibits fluorescence. Fluorescence refers to their ability to emit the light of a specific color after being exposed to the light of some other color. Due to their ability to emit light of a specific color, the fluorescent molecules can be easily visualized in the cells or body. To track the location of a non- fluorescent molecule, it can be attached to a fluorescent molecule and the respective location can be visualized by observing the emission of light.

Proteins do not have the ability of fluorescence. To confirm the movement of a specific protein from the cytoplasm to the nucleus, it is labeled with a fluorescent molecule. The emitted light by the fluorescent molecule tells the location of the protein in the cell.
