DNA Sequence of Genghis Khan’s Descendant

Scientists in China have completed the genome sequence for Genghis Khan’s direct descendant—the first complete genome sequence from a representative of the Mongolian population. The unnamed man is Khan’s 34th- generation descendant, who was chosen for his fully defined family pedigree dating back to the 13th century, and the absence of intermarriage with other ethnic…

Bobtails and DNA Testing

Although the bobtail in the classic Christmas carol refers to “the style of the horse’s tails—a tail cut short or a tail gathered up and tied in a knot,” the fashion is not limited to horses. In fact, some dog breeds also sport a bobtail—and some animal owners been known to artificially dock a dog’s…

Immigration DNA Testing

The OC Register is running a series of stories entitled “Faces of Immigration,” featuring real-life stories of people whose lives have been affected by immigration. This week’s article features how a DNA test allowed a 19-year-old Vietnamese boy to finally reunite with his mother: he was 10 years old when his immigration case was first…

DNA Testing for Native Americans

A recent article in ScienceNews discusses recent research on the genetic diversity found in Native Americans today. DNA testing has been used to trace the population shifts that occurred when European explorers reached the Americas. A group of scientists have observed a striking change in the DNA of Native Americans that may correlate with the…

DDC Unveils Cell Line Authentication Services at Scientific Conference

DDC’s associate laboratory director, Dr. Thomas Reid, will be presenting a scientific poster detailing the techniques used in DDC’s cell line authentication service this weekend at the American Society of Cell Biology (ASCB) Annual Meeting in Denver, Colorado. The integrity of cell lines used in scientific research has been shown to be compromised in many…

DNA and Thanksgiving

Discovery magazine has compiled a slideshow featuring what scientists have discovered or developed regarding the various items on your Thanksgiving menu. Entitled “The Genome of Your Thanksgiving Supper,” the 2010 article provides interesting facts about the turkey genome, which contains 80 chromosomes (humans have 46), and how potatoes and tomatoes are genetically related. The study…

Decoding the Secret to Longevity

Scientists are examining the DNA of centenarians, looking for a possible genetic link to longevity. George Eberhardt, 107 years old, is one of 100 healthy centenarians taking part in a study that ultimately hopes to identify genes that prevent age-related diseases and disorders. This study is part of the Archon Genomics X Prize competition, funded…
