Researchers commonly use DNA technology to create recombinant DNA that has a "glowing" protein product. Which of the following is a benefit of this technology?

A)This technology provides proof to nonscientists that genetic engineering is safe.
B)Organisms that express this gene can obtain energy through photosynthesis rather than consumption.
C)The genes for glowing proteins are easier to clone than other genes.
D)Glowing proteins allow scientists to see where a particular gene is expressed in living cells.
