In an eukaryotic cell‚ DNA is tightly packaged into the nucleus. For a human cell‚ DNA measures approximately 2 meters‚ with its diameter being 2 nm. The total length of DNA present in one adult human is nearly 2.0 × 1013 meters‚ which is equivalent to nearly 70 trips from the earth to the sun and back.
