How far would all the DNA in a single body stretch if unraveled?

The DNA in a single human body contains an extraordinary amount of genetic material. If you were to unwind all the DNA found in the cells of an average human body, it has been estimated that it would stretch approximately 67 billion miles. This distance is immense enough to extend from the Earth to the Sun and wrap around it about 400 times.

This estimation takes into account the vast number of cells in the human body, which is around 37 trillion, each containing a complete set of DNA that can be several feet long when fully unraveled. The incredible length of DNA underscores both the complexity and the efficiency of biological systems.

The other options, while they involve significant distances, do not accurately represent the measurement of human DNA. The distance to the nearest star or to Mars is not sufficient when compared to the staggering stretch of DNA that exists in one human body, and while the distance to the Moon may sound impressive, it pales in comparison to the immense reach of human DNA to the Sun.
