In a typical eukaryotic cell, where is most of the cell's DNA located?

• A. In lysosomes, where it is stored and protected from degradation
• B. In the nucleus, packaged as chromatin
• C. In the cytosol, free-floating as circular DNA
• D. In the Golgi apparatus, where it is sorted for secretion

Answer: (B)

Verified step by step guidance

1. Recall the main organelles in a typical eukaryotic cell and their functions, focusing on where genetic material is stored.
2. Understand that DNA in eukaryotic cells is primarily located in the nucleus, where it is organized as chromatin, a complex of DNA and proteins.
3. Recognize that lysosomes are involved in degradation of cellular components, not storage of DNA.
4. Note that free-floating circular DNA is characteristic of prokaryotes or mitochondria, not the cytosol of eukaryotic cells.
5. Remember that the Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids, not storing DNA.
