In a eukaryotic cell, where is the DNA primarily located?

• A. Mitochondria
• B. Cytoplasm
• C. Nucleus
• D. Chloroplast

Answer: (C)

DNA in a eukaryotic cell is stored mainly in the nucleus, organized as chromosomes wrapped around histone proteins within chromatin. This arrangement lets the cell tightly package a large genome and control access to it during transcription and replication. There are additional small genomes in organelles like mitochondria (and chloroplasts in plants and algae), but these contain only a tiny subset of genes compared to the nuclear genome. The cytoplasm itself doesn’t house the main DNA stock, even though it’s the site where many cellular processes like translation occur. So, the nucleus is the primary location of DNA.
