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.

How much information is on a strand of DNA??
     Carla Easter, Ph.D.: Creates and implements genetic education programs. Works with the branch to create science education products for high school students. The amount of information is dependent on the region of the DNA you are looking at. Less than than 3% of the genome appears to encode proteins, but researchers are discovering that significant parts of the remainder of the DNA sequences are actively expressed and may be playing a role in regulation or possibly some unknown role.
