Answer:
The correct answer is a DNA is integrated into a chromosome and maintained indefinitely.
Explanation:
During DNA Cloning the target DNA is cleaved by restriction endonuclease result in the generation of target DNA fragments.
A suitable vector is chosen and the DNA of that vector is cut with same restriction enzyme which lead to generate a gap in the vector DNA.
A target DNA fragment is then integrated with the gap region of the vector and is maintained indefinitely .
