The human genome includes all the genes and other genetic
information contained in human cells, and sequencing it is a monumental feat that's been
compared to the U.S. moon shot or even the Manhattan Project, minus the fireworks.
It is a text 3.5 billion years in the making, and the fact that it
is written in a language we don't fully understand doesn't diminish the excitement. It
might take a century to completely decipher the genome, but year by year, that quest will
provide fresh insights into what sets humans apart from other animals.
