But what are the moral dilemmas raised by this new technology? Will it help or hurt us to know our genetic destiny? What if such information falls into the hands of insurance companies, employers, or prospective mates? One thing is for certain: the new era of personalized, gene-based medicine is relevant to everyone, and soon we may have to choose whether to join the ranks of the DNA generation.
