In experiments to test whether a protein can enter the nucleus why would proteins be labeled with fluorescent molecules? Large proteins containing a nuclear localization signal ( NLS ) bind to the nuclear pore and enter the nucleus without any expenditure of energy. False A small protein is injected into a cell and observed in the nucleus a short time later. Nucleoplasmin is a nuclear protein. This protein was divided into two segments and linked to the same large cytoplasmic protein generating two fusion proteins. After injecting these fusion proteins into a cell one of the proteins was found in the nucleus and the other in the cytoplasm . In experiments to test whether a protein can enter the nucleus why would proteins be labeled with fluorescent molecules ?-To make the proteins bigger-To give the protein molecules energy-To make the proteins easy to see-To target the proteins to the nucleus Nucleoplasmin is a nuclear protein. This protein was divided into t...
