where is the dna located in a eukaryotic cell? ribosomes nucleus cytoplasm cell membrane

In a eukaryotic cell, DNA is primarily located in the nucleus. The nucleus serves as the control center of the cell, containing the cell's genetic material organized into chromosomes. This DNA is wrapped around proteins called histones, forming a complex known as chromatin, which helps in packaging the DNA and regulating gene expression.

While a small amount of DNA can also be found in mitochondria (the energy-producing organelles) and in chloroplasts (in plant cells), the majority of the genetic material is housed within the nucleus. The other options you provided—ribosomes, cytoplasm, and cell membrane—do not contain DNA. Ribosomes are the sites of protein synthesis, the cytoplasm is the fluid that fills the cell, and the cell membrane is the outer layer that protects the cell.
