As per the NIH-NIGMS, a single human cell contains a 5.8 to 6 feet long DNA strand. So it lengths up to ~2m.

The length of male and female human DNA of a single cell in centimeter is 205cm and 208. 23cm, respectively (Article from BMC).

If we consider 100 trillion cells in our body, the total length of all human DNA is so large that we can do a round trip from Earth to Sun many times.

The total length of all human DNA is 107. 826 billion Km (67 Billion miles). We can make a 1,50,000 round trip from Earth to the Moon.

Interestingly, the length of all body DNA is 2 or more times the diameter of the solar system.

With a total DNA, we can wrap our earth millions of times. Isn’t it amazing!

Even, we can stretch all of our DNA to our nearest galaxy which is 2.5 million years ago, two times.

A cell’s mechanism called supercoiling helps DNA to interact with protein and arrange on chromosomes.
