Health IT meets the genome

August 1, 2008

Meet Joe’s genes. Residing within each of his body’s 100 trillion cells are 23 pairs of chromosomes containing as many as 25,000 genes made up of more than 3 billion base pairs of nucleotides, the structural units of DNA and RNA. If Joe could transfer that data to a CD, the file would occupy as much space as his copy of Led Zeppelin IV. (Health IT)
