Richard Brewer, administrator for the Brewer DNA Project, sent this link in an e-mail out to all members of the Brewer DNA Project last week, and I'd like to pass it on to others who visit this site. Richard's words:
"Because each of you has submitted samples of your DNA for testing of the Y-Chromosome to find genetic matches with other participants, I thought you might be interested in seeing just exactly what your DNA and chromosomes look like in action on a molecular level when the cells in your body divide, copying each DNA strand with near perfect precision. Of course every now and then a random error occurs, generating a mutation, which is what we have been using to identify related persons. When you look at the process occurring every day in your cells, it is a wonder that any continuity persists. But it does. The FTDNA lab analyses the Y-chromosome that exists in the cells of a male. In this TED talk you will see illustrated a generic chromosome having its genetic information copied as the cell is divided."
The video, Drew Berry: Animations of Unseeable Biology, is found on the TED Talks website, which itself is one website that you may want to spend some time exploring. It features videos and talks on a wide range of subjects. Hope you find it as fascinating as I did.
