2008 National DNA Day Online Chatroom Transcript

This is just one question from an archive of the National DNA Day Moderated Chat held in April 2008. The NHGRI Director and many genomics experts from across NHGRI took questions from students, teachers and the general public on topics ranging from basic genomic research, to the genetic basis of disease, to ethical questions about genetic privacy.

Kris Wetterstran: You said that there are more cells from microscopic organsisms on our bodies than our own cells. Does their DNA affect our own DNA ?
     Kris Wetterstrand, M.S.: Working with the Sequences, Maps and Bacterial Artificial Chromosome (BAC) Libraries Program and the ENCODE (ENCyclopedia Of DNA Elements) project. The DNA of microbes doesn't necessarily affect our DNA. But the their presence definitely affects how our bodies work, for example how we digest food or how we are susceptible to infection.
