Are Ashkenazi Jews descended from just four Jewish women?

In a fascinating study published in 2006, it was shown that 40\% of all Ashkenazi Jews are descended from just four Jewish women who lived more than 1,000 years ago. The study concluded that if someone bears specific mitochondrial DNA markers, there is a 90-99\% chance that he or she is descended from one of these Jewish women. 1

Is there such a thing as Jewish DNA?

How can you tell if a person is Ashkenazi?

In theory, mitochondrial DNA (which you get only from your mother, and she gets only from her mother, etc.) can show whether a person is Ashkenazi, but only in about half of the Ashkenazi population, and those are believed to be descended from converts, because they don’t share mitochondrial DNA with Jews who are not Ashkenazi.
