Your DNA holds over 60 zettabytes of data

Your DNA holds over 60 zettabytes of data. That’s about 5,000 times the estimated information content of all human knowledge.

  • There are four nucleobases in DNA, adenine [A], cytosine [C], thymine [T] and guanine [G], which require 2 bits each to store
  • Each haploid cell (sperm or egg) in your body is made of 3,234.83 million base pairs
  • Your somatic cells have twice as many base pairs with one set coming from your dad and the other coming from dear old mom
  • There are an estimated 37.2 trillion cells in your body
