DNA: Our Genetic Blueprint

Course video 24 of 32

What does your DNA say about you? You may have heard that you share 99% of your genetic material with everyone else on the planet. That's true, but this week we're going to take a look at the less than 1% that makes you unique. We'll kick off by discussing the Human Genome Project, the massive scientific collaboration that mapped out the sequence of all our genetic material. The technologies developed while mapping out the human genome ushered in a new age in DNA research. Now, genome-wide association studies can analyze massive amounts of data, searching for genetic variations that are associated with particular diseases. Pharmacogenomics may help determine which drugs are likely be most effective for you. Genetic genealogy tests (such as Ancestry DNA, 23 and Me, and Family Tree DNA) will allow you to trace random mutations in your DNA that can provide clues to your ethnic heritage. As an added bonus, we'll discuss whether it would be possible to revive extinct species by studying ancient DNA.
