In the 1980s, British researchers demonstrated that a human gene could be inserted into the cells of a particular strain of yeast that had a defective gene. Once inserted,
the human gene worked perfectly in the yeast. What correctly explains this
occurrence?
The yeast cell and a human cell carry the same type of gene.
O The yeast cell mutated the gene to make it compatible.
O The human cell changed the yeast cell's genetic information once it was inserted.
O The human cell and the yeast cell developed a symbiotic relationship.
