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.

As we know, thermophiles can survive at high temperatures above 100 degrees.How do they protect their DNA from getting denatured?
     Kris Wetterstrand, M.S.: Working with the Sequences, Maps and Bacterial Artificial Chromosome (BAC) Libraries Program and the ENCODE (ENCyclopedia Of DNA Elements) project. While I am no expert on DNA at high temperatures, I believe that thermophiles use specialized proteins to protect the DNA degradation.
