Question

7. When cell transformation is successful,the recom- binant DNA a. undergoes mutation. b. is treated with antibiotics. c. becomes part of the transformed cell's genome. d. becomes a nucleus.

Answer 1

The correct answer is C. The recombinant DNA becomes part of the transformed cell's genome.

Answer 2

## Step 1 Cell transformation is a process where a cell takes up DNA from its environment. This DNA is often referred to as recombinant DNA. ## Step 2 Once the recombinant DNA is taken up, it becomes a part of the host cell's genome. This is because the cell's DNA is usually broken down and reassembled, which is why the DNA can be incorporated into the host cell's genome. ## Step 3 This process does not necessarily cause a mutation. Mutations are changes in the DNA sequence, and while the recombinant DNA can cause mutations, it is not a guaranteed outcome of cell transformation. ## Step 4 The recombinant DNA does not become a nucleus. The nucleus is the part of the cell that contains the DNA, but the DNA itself does not become a nucleus. ## Step 5 The recombinant DNA is not treated with antibiotics. Antibiotics are used to kill bacteria, not to treat DNA.
