उत्तर
The total DNA from a single human cell, if fully stretched out, would measure approximately 2.2 metres in length. This extreme length must be compacted approximately 10⁶-fold to fit within the nucleus, which is only about 1 micrometre in diameter, highlighting the necessity of sophisticated DNA packaging mechanisms.
