Guida verificata passo dopo passo1
Understand that in eukaryotic cells, DNA is stored and organized within a specific membrane-bound structure.
Recall that the mitochondrion contains its own DNA but is not the main site for the cell's chromosomal DNA packaging.
Recognize that the cytosol is the fluid portion of the cytoplasm and does not contain chromosomes or DNA packaging structures.
Know that the plasma membrane encloses the entire cell but does not contain DNA or chromosomes.
Conclude that the nucleus is the organelle where DNA is tightly coiled and packaged into chromosomes in eukaryotic cells.
