Scientists inserted a gene from a desert plant into a crop plant. The crop plant then produced a protein that helps it to survive drought. Why is the crop plant able to make this protein from the desert plant gene?
The two plants are the same species, so their genes are identical.
All organisms use the same genetic code to make proteins from genes.
The gene changes all of the crop's DNA into the desert plant's DNA.
The desert plant gene makes the crop plant cells divide more quickly.
