## How long is your DNA end to end?

6. That’s how many feet long the DNA from one of your cells would be if you uncoiled each strand and placed them end to end. Do this for all your DNA, and the resulting strand would be 67 billion miles long—the same as about 150,000 round trips to the Moon.

## How is DNA length calculated?

The total length of the DNA can be easily obtained by applying a simple equation. The total length of DNA (double helix) = total numbers of base pairs × distance between two consecutive base pairs.

## How long is a single strand of DNA?

As is known, the persistence length and the length per base of dsDNA is 50 nm [46] and 0.34 nm [47] respectively. The persistence length of single-stranded DNA, as a kind of flexible polymer, cannot be larger than 50 nm.

## How many times can your DNA wrap around the Earth?

Each of us have around 50 trillion cells (50,000 billion). If we took the DNA from all of those cells and laid it out in a linear fashion, it could wrap around the earth 2.5 million times, or reach to the sun and back 300 times [3]!
