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.

Would you say DNA or environmental triggers are the leading cause of cancer? [mason]
     Heidi Parker, Ph.D.: Comparing the dog genome to the human genome in an effort to answer questions about disease in both dogs and humans. DNA is definitely the leading cause of cancer, when something goes wrong in the DNA it can cause the cells to grow out of control and a tumor is formed. Some of these problems are inherited while others happen spontaneously during cell division. There are environmental factors that can increase the possibility of getting one of these spontaneous mutations by interfering in the DNA strand.
