Where does DNA replication take place in eukaryotic cells?

• A. In the cytoplasm
• B. In the ribosomes
• C. In the nucleus
• D. In the mitochondria

Answer: (C)

Verified step by step guidance

1. Understand that eukaryotic cells have a defined nucleus, which houses the cell's DNA.
2. Recall that DNA replication is the process by which a cell duplicates its DNA, ensuring that each new cell receives an exact copy of the DNA.
3. Recognize that in eukaryotic cells, the nucleus is the organelle where the DNA is located and where replication occurs.
4. Consider the role of other organelles: the cytoplasm is where many metabolic processes occur, ribosomes are involved in protein synthesis, and mitochondria have their own DNA but are not the primary site of nuclear DNA replication.
5. Conclude that DNA replication in eukaryotic cells takes place in the nucleus, as it is the location of the cell's chromosomal DNA.
