उत्तर
The eukaryotic cell nucleus has a diameter of approximately 10⁻⁶ m or 1 micrometre. Despite this very small size, the nucleus must contain and organise the entire complement of genomic DNA (approximately 2.2 metres in length when stretched), requiring multiple levels of hierarchical DNA packaging.
