Question

Bioluminescence is the emission of light by a living organism. It occurs naturally in many organisms. For example, one species of jellyfish has a protein that causes it to glow in a bright, green color. Scientists have isolated the gene that produces the bioluminescence protein and inserted the gene into the embryos of tetra fish. This results in tetra fish that produce a green glow.



Which statement explains why the tetra fish are able to produce a green glow?
A.
The protein that produces green light was taken from the jellyfish and injected into the tetra fish.
B.
The tetra fish were bred with jellyfish, which produced offspring that can make the protein for green light.
C.
The genetic material of both the jellyfish and tetra fish were combined, which created a fish with all traits from both species.
D.
The inserted gene gave the tetra fish the ability to make the protein that produces green light.

Answer 1

D.

The isolated gene was inserted into the tetra's genome, so the fish can now produce the jellyfish protein that emits green light.
