It isn’t too much more than a decade ago that we first fully described the information content contained by human DNA. That lengthy, intricate code, as the leader of the Human Genome Project eloquently states, is the language describing our biological construction and operation.
DNA is amazing stuff. While the general content of the genetic code written on that molecule is now known, each of us is still as unique as a snowflake. Although we all possess the same basic set of genes, we all carry a wide variety of variations within those genes, and this recipe makes up our individual genotype. Furthermore, the interaction of these genes with environmental factors is also unique, so our phenotypes — our observable characteristics — are also different.
