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 many genes are there in a human genome?
     Pnina Laric, M.S.: Coordinates the summer and post-baccalaureate internship and training programs at NHGRI. Currently, we think there are about 20,000 genes in the human genome. Interestingly enough, that number continues to go down as we do more and more research. Not too long ago, we thought that number was closer to 100,000!
