Where does replication take place?

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

Answer: (A)

DNA replication copies the genetic material before cell division, and in most eukaryotic cells that process occurs in the nucleus. The nucleus houses the cell’s DNA and provides the necessary enzymes and organized environment for duplicating chromosomes, ensuring both copies stay identical as the cell prepares to divide. The other structures have different roles: the cytoplasm is where many metabolic processes and protein synthesis occur, lysosomes are for digestion and waste processing, and ribosomes build proteins. So the nucleus is the proper site for replicating the genome.
