Question

Which of the following statements is NOT true regarding green fluorescent protein (GFP)?

A: It occurs naturally in jellyfish and other organisms that flow in the dark.
B: It can be used to follow the activities of tagged molecules in living cells.
C: The gene that encodes GFP has been incorporated into the DNA of other organisms and expressed as fluorescence.
D: GFP does not require an additional cofactor to absorb and emit light.
E: Research into cloning this gene for molecular biological studies is not yet complete.

Answer 1

The statement that is not true about GFP is that research into cloning the gene for molecular biological studies is not yet complete, as GFP has been extensively researched and used as a marker in the field of genetic engineering.

Step-by-step explanation:

The statement that is NOT true regarding green fluorescent protein (GFP) is E: Research into cloning this gene for molecular biological studies is not yet complete. Cloning and research on the GFP gene has been extensively carried out, and GFP has been widely used as a genetic marker in many organisms. The other statements A through D about GFP are indeed true:

• A: It occurs naturally in jellyfish and other organisms that glow in the dark.
• B: It can be used to follow the activities of tagged molecules in living cells.
• C: The gene that encodes GFP has been incorporated into the DNA of other organisms and expressed as fluorescence.
• D: GFP does not require an additional cofactor to absorb and emit light.
