DNA, once the exclusive domain of scientists in research labs, is
now the darling of popular and social media. With personal genetic
testing kits in homes and GMO foods in stores, DNA is an
increasingly familiar term. Unfortunately, what people know, or
think they know, about DNA and genetics is often confused or
incorrect. Contrary to popular belief, for instance, genes don't
"skip a generation" and, no, human DNA is not "different" from DNA
of other species. With popular misconceptions proliferating in the
news and on the internet, how can anyone sort fact from fiction?
DNA Demystified satisfies the public appetite for and curiosity
about DNA and genetics. Alan McHughen, an accomplished academic and
public science advocate, brings the reader up-to-speed on what we
know, what we don't, and where genetic technologies are taking us.
The book begins with the basic groundwork and a brief history of
DNA and genetics. Chapters then cover newsworthy topics, including
DNA fingerprinting, using DNA in forensic analyses, and identifying
cold-case criminals. For readers intrigued by the proliferation of
at-home DNA tests, the text includes fascinating explorations of
genetic genealogy and family tree construction-crucial for people
seeking their biological ancestry. Other chapters describe genetic
engineering in medicine and pharmaceuticals, and the use of those
same technologies in creating the far more controversial GMOs in
food and agriculture. Throughout, the book raises provocative
ethical and privacy issues arising from DNA and genetic
technologies. With the author's comprehensive expertise, DNA
Demystified offers an informal yet authoritative guide to the
genetic marvel of DNA.
