New video posted: How long is the DNA in a human cell?

In this video, I calculate the length of the DNA in one human cell, and my answer may surprise you.

How long do you think? 0.2 mm, less? 2 mm, 2 cm, 2 m, 2 km? Watch the video to find out.

The video walks you through the math I used to calculate the length of DNA, and then I will reveal the length it would be if the cell were the size of a football.
