2005 National DNA Day Online Chatroom Transcript
This is just one question from an archive of the National DNA Day Moderated Chat held in April 2005. 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 fast does DNA replicate?
| |
Belen Hurle, Ph.D.: Great question, Michelle. Bacteria can replicate about 100,000 bases per minute. Eukaryotic DNA polymerases are slower than bacterial DNA polymerases and can replicate about 500 - 5,000 bases per minute. To make up for the slower replication, eukaryotes have more origins of replication. |
