Where is the DNA primarily located in a eukaryotic cell?
A
In the ribosomes
B
In the cell membrane
C
In the cytoplasm
D
In the nucleus
Verified step by step guidance1
Understand the structure of a eukaryotic cell: Eukaryotic cells have a defined nucleus, which is a membrane-bound organelle that houses the cell's genetic material.
Identify the role of the nucleus: The nucleus is the control center of the cell, containing most of the cell's DNA, which is organized into chromosomes.
Differentiate between organelles: Ribosomes are involved in protein synthesis and are not the primary location of DNA. The cell membrane is the outer boundary of the cell and does not contain DNA. The cytoplasm is the gel-like substance within the cell membrane, excluding the nucleus, and contains organelles but not the primary location of DNA.
Recognize the primary location of DNA: In eukaryotic cells, the majority of DNA is located in the nucleus, where it is protected and organized for replication and transcription.
Conclude with the correct answer: Based on the understanding of eukaryotic cell structure, the DNA is primarily located in the nucleus.
