AI-згенерована художня схема, що пов’язує ДНК у клітинному ядрі з оцінкою довжини, зіставленою з масштабом Сонячної системи; не біологічне фото і не точний масштабний графік. Prompt: educational illustration of DNA uncoiling from a nucleus toward Pluto, no numbers/text, distinguish a cell panel from whole-body estimate.

If the nuclear DNA from all cells in a human body were uncoiled and laid end to end, one published estimate gives about 6.2 billion kilometers—roughly 41 Earth-to-Sun distances, not a trip to Pluto and back. The result depends on the number of nucleated cells, ploidy, and which cell types are counted. A typical diploid cell alone contains about 2 m of DNA. [1–3]
