Which of the following describes the organization of DNA within a eukaryotic cell?

• A. DNA is organized into linear chromosomes within the mitochondria.
• B. DNA is organized into circular chromosomes within the nucleus.
• C. DNA is organized into circular chromosomes within the cytoplasm.
• D. DNA is organized into linear chromosomes within the nucleus.

Answer: (D)

Verified step by step guidance

1. Understand that eukaryotic cells have a defined nucleus, which is a key feature distinguishing them from prokaryotic cells.
2. Recall that DNA in eukaryotic cells is organized into structures called chromosomes, which are located within the nucleus.
3. Recognize that eukaryotic chromosomes are linear, meaning they have two ends, unlike the circular chromosomes found in prokaryotic cells.
4. Consider the location of DNA in eukaryotic cells: it is primarily found in the nucleus, not in the mitochondria or cytoplasm.
5. Conclude that the correct description of DNA organization in a eukaryotic cell is that it is organized into linear chromosomes within the nucleus.
