Allow Me To Blow Your Mind

Sit back comfortably, I’m about to blow your mind.

A diploid genome inhabits every cell in the human body. This genome consists of roughly 6 billion DNA base pairs. Liken DNA pairs to balls of string wrapped around proteins in the cell. Unravel the string it stretches out to a couple meters. A human body has 37 trillion cells (that’s 37,000,000,000,000 give or take a few). Lining up all DNA in a human body would stretch 74 trillion meters, or 74 billion kilometers – roughly 6 round trips to once a planet Pluto. That’s a mighty long strand of humanity.
