Answer:
The Correct answer is second - Both plant and animal cells have a nucleus, where DNA replication takes place.
Step-by-step explanation:
Plants and animals are eukaryotic animals that means they have contain membrane-bound organelles inside the cell which performs specific functions. They also contain a well-organized nucleus which is present in the center of the cell whereas prokaryotes do not contain any nucleus.
Both animal and plants have a nucleus which contains the genetic material inside it. Nucleus is the site for DNA replication and transcription in both plant and animal cell. Nucleus contains all the information about the cell so it is also known as the brain of the cell.
Therefore, the correct answer is both plant and animal cells have a nucleus, where DNA replication takes place.
