- Fireflies produce light inside their bodies. The enzyme luciferase is involved in the reaction that produces the light. Scientists have isolated the luciferase gene. A scientist inserts the luciferase gene into the DNA of cells from another organism. If these cells produce light, the scientist knows that which of the following occurred? The luciferase gene mutated inside the cells. The luciferase gene was transcribed and translated. C The luciferase gene destroyed the original genes of the cells. The luciferase gene moved from the nucleus to the endoplasmic reticulum. 2,279 MAR étv 12 MacBook Air DII DDCan I get a breakdown on usher sydrome affected mutations? thank you!3.
