INFOGRAPHIC 20.1 HUMANS ARE GENETICALLY SIMILAR
The human genome includes 3 billion nucleotide base pairs. Its entire sequence of A, G, T, and C nucleotide bases would fit into 200 phone books, each 1,000 pages long. When stacked, the phone books would reach to the top of the Washington Monument in Washington, D.C. That’s 200,000 pages of genetic code!
