Question

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.

Answer 1

O The yeast cell mutated the gene to it compatible.

Answer 2

The correct explanation of the statement that the human gene worked perfectly on the yeast is the yeast cell mutated the gene to make it compatible.

The correct option is (B).

What is gene transfer?

Gene transfer is a method of transferring gene into other animal through DNA recombination technology.

Both germ line and somatic mutations are possible with gene transfer.

The activity of a whole metabolic pathway is affected when the concentration of a signal peptide, such as growth hormone, is increased.

Gene transfer has a great importance in science and technology.

Thus, in the cases, the gene mutated itself to work perfectly on a yeast cell. The correct option is (B).
